Itâs always funny to me, the blood purity debate. Going by what we knowâŚ
Firstly, the author has stated in various times that the mixing of magical blood with muggles does not produce a higher incidence of squibs, and that squibs are accidental, with some of these statements being âin universeâ, so to speak, as if from history books. We see evidence otherwise, including the story of the wizard Thaddeus Thurkell who had seven sons who were all squibs.
(More recently we also see the Page family who were a muggle and a witch couple whose three children only have one magical child among them, as well as the Merriweather family who had one squib child and another magical one, and the magical child went on to have a squib child too. But those one could potentially argue away since theyâre not created by the original author in the series, as some do)
We also have the author stating that muggleborns are the result of magical ancestry through squibs, even though it hasnât been proven in-universe. Unlike the previous statement and in line with the incidence of squibs in single families, this indicates that magic is a hereditary trait although can go dormant for generations until just the right match happens.
Additionally, we also have the author stating that Vernon Dursley is so strongly muggle that even his son still wouldnât be able to have magical children. This goes against the first statement above, and very directly. If a person can be so strongly anti-magical, then it follows that magical folk who try to have children with this sort of muggles would always have squib children. Therefore, it is simply false that marrying muggles does not affect getting squib children.
The evidence is clear, it all points to magic being a hereditary trait (with some accidents of birth possible in fully magical families), and there are also genes that are so strongly anti-magical that they overcome any magic given by the other parent. Once again I come to the conclusion that blood purists have the facts more fully down than Dumbledore, disregarding any extremist propaganda during the Second Wizarding War, even if their emotional reactions to it put off some other people.
âŚ.yeah. It just amazes me how people still continue to be confused about this.
JKTERF clearly just had nothing she wanted to say with this metaphor, so it's not clearly explained in text and such.
I think it makes sense that muggle genes are stronger than magical genes, since there are way more muggles in text than magical people, but I'm also curious how this affects creature heritage. If for example, Apolline Delacour had a child with Vernon Dursley, what would that child be (jusing these two characters because Vernon is the only muggle stated to be incapable of having children and Apolline is the only age appropriate halfbreed)? Because Vernon is apparently incapable of having magical children, but Apolline is not entirely human. Would they simply be incompatible? Would every child result in miscarriage?
It feels like there's a massive hole in the worldbuilding of this series when it comes to how magical lineage actually works, especially with halfbreeds. Like, when would a persons muggle heritage become null and void? When does creature heritage stop playing a role in magical ability? Does it never stop? Is that why certain families have specific powers, because somewhere in their ancestry there's a specific creature? Are halfbreeds capable of having squib descendants? If muggle genes are stronger, is that why wizards are scared of mixed marriages? Because they don't want to be bred out of existence?
I've always understood that the blood purity thing was probably meant to be comparable to racism or xenophobia, admittedly a bad comparison, but a comparison nonetheless, and honestly the choice to depict muggles as a minority compared to wizards was always weird, but it's especially weird if you add racial coding to it. Because, as an Australian, I look at Aboriginal Australian's and think that honestly, I'm not surprised some of them are scared of marrying people from outside that community. They take up 1% of the Australian population, and historically, White colonisers did try to breed the Black out of them. So, as much as the muggle-borns are definitely the characters who are coded the most to be Black, Brown and/or Asian, wizarding society as a whole being scared of being wiped out be the larger populous they need to hide from definitely complicates things.
I'd almost want to compare it to what happened with Israel, where Jewish people were prosecuted in the Holocaust and thus felt that forming their own community in their homeland was the only place they'd be safe, and turned Zionist Judiasm into a borderline cult, using propaganda to say that Zion was the only safe place for them and letting anyone else in would be dangerous, therefore genocide is the only way to defend themselves. It's definitely not on purpose, and I highly doubt JKTERF wanted readers to view the Death-Eater's as victims turned predators, especially since she's retconned them and said they're now a metaphor for LGBTQ+ activism (I could go on about what this means for the story) and she's even a Holocaust denier now, but it is the only real world example I can currently think to compare them to that most people would recognise.
The Death-Eaters are not victims, nor are they good people in universe, but the way the worldbuilding is done and the things they believe in do set you up to think about that kind of thing. It's even worse when you consider how many of them are raised since birth to believe Voldemort's dogma and how many of the Death-Eaters with actual characterisation were children when they joined what is essentially a domestic terrorist group with fascist beliefs that borders on a cult.
The fact that muggle blood clearly does have an impact on the existence of magic and the ability to produce a magical child heavily complicates the pureblood supremacist beliefs, because as much as they shouldn't care that intermixing creates mixed kids, it is functionally erasing their culture. Doesn't make genocide justified, but it does make the world messy and the already botched theming even harder to get a handle on.
Hmm. Thereâs a lot there I could comment on in theory, and to be fair I wouldnât even consider it for a complete stranger, it tends to get complicated when you add real world politics and âthemesâ and opinions on writing quality into the mix. And yes, she is total human garbage.
However. I wouldnât consider her later statements about real world comparisons as saying a single thing about the books, rather theyâre about herself and herself only. Before any LGBTQ+ rights comparisons, before any nazi/WW2 comparisons, there are the books themselves and the books are written with extremely crystal clear direct comparisons to IRA - their mission, their operations, even their masks of choice (the white masquerade masks âDeath Eatersâ wear are a movie invention just as much as wizards in muggle clothing are, in the books the Death Eaters are characterized by black ski masks basically, supplemented with deep, black hoods). She can claim something else until sheâs blue in the face, but whatâs written in the books is in the books.
The above is also why I skip basically any and all complaints about supposed themes and real world comparison attempts that I see. I donât mean this to be offensive in any way to anyone, but if you canât read the books for what is there and familiarize yourself enough with British history to see a goose for a goose, well. Nobody like that is very qualified to comment on the themes and messages the books might or might not have. That is just trying to impose outside perspectives and foreign political issues onto very British history and culture, of course itâs not going to fit. Itâs no wonder they think those supposed messages and themes are nowhere to be found. Youâre looking for someone elseâs preconceived notions and someone elseâs history. Not whatâs actually there.
Itâs nice to relate to other cultures and other times through finding familiar threads to compare to your own culture and times. But you should never make that a cornerstone of your understanding of a text. If the text wasnât written for issues youâre familiar with then it simply wasnât written for that. It does not make the text faulty, it means you donât have the necessary framework to understand it.
I find this the most major issue in HP analysis actually, how people keep deciding beforehands what should be there and then raging when what they find doesnât match. Thatâs not how analysis works. Harry Potter is deeply, deeply British series, it was not written (planned?) with international audiences in mind.
So. To continue on the blood purity issue since thatâs what I started with, itâs all about the question of just how much a dominant culture can integrate into an oppressed minority, even if theyâre born such that they might otherwise be considered part of the minority. In this case, the closest comparison is English people moving to Ireland - are their kids Irish? Really and truly? Despite the centuries of violent oppression? Despite doing nothing to adopt Irish customs and language? Despite them simply having an accident of birth and taking the title for themselves? The citizen/member of a culture issue muddled this too, since Irish and Irish are not necessarily the same thing. People in majority countries might be accustomed to thinking immigrants are always entitled to be thought of as citizens no matter which culture they follow (unless theyâre fascists of course), but what happens when the immigration is actually incomplete integration into (obliteration of) a culture that is a historically oppressed minority? What protective measures go too far? What can be permitted to preserve a whole way of life? And what happens if we fail to do anything about the hordes of majority oppressors at the borders? There will always be people who like their own culture and would prefer to pass it on, so what happens when that is threatened? Itâs not a viewpoint often brought up in western mainstream media, for understandable reasons being that the majority voices are just that. Majority. Not the minorities trying to survive. Those are big questions for a middle class British white woman to put into family-friendly literature. She falls far short, and she identifies as too much UK and not enough Ireland which comes through loud and clear (and even among Irish IRA never had universal support). To be fair though, even if she did want to genuinely explore these questions (and we donât know if she did or not), she would have been hampered by the intended audience and resulting editorial oversight especially. Canât have the bad guys having real points in this genre! But bad person must have always been thoroughly rotten, and all that, so there is zero discussion of what might have been if this theme was explored better, even in the rare instances people donât get overtaken by their inherent US centrism and think the DEs are nazi equivalents.
Iâve seen a lot of thoughtful depictions of these questions in fic, but not so much meta. Itâs too much of a hot button issue - to be fair, it is also why I personally donât generally participate in the âthemesâ and other shit discussions. There are too many people committed to taking fictional world issues too personally and become incapable of seeing anything but the real world hot button issues relevant to their own lives. Not to mention the inability to acknowledge even bad people can create beauty, as mentioned above. Whenever I look into the âthe writing is badâ argument for example, I never find anything particularly substantial. It always seems to boil down to âbad person must have bad writingâ - in some cases âpopular book must have bad writingâ but that was an argument more commonly used 10+ years ago rather than the present day.
(Do not be surprised if I simply fail to answer should you choose to respond to any of the above, this account is a fandom getaway not my politics sideblog and Iâve elaborated about as much as I care to. Feel free to add your thoughts though!)
Half-breeds! Yes, itâs a thoroughly fascinating question about how it affects things. There is no evidence of course, but to me it seems logical that at least the most magical species canât interbreed with muggles who have anti-magic genes such as Vernon Dursley. Like veela - there is no way they could exist without magic since they transform, throw fireballs, and have a supernatural allure that pulls in certain others based on attraction. So I personally think any such attempt would either result in a spontaneous miscarriage early on or the egg wouldnât be fertilized in the first place. Itâs harder to say with other species such as giants - they donât seem particularly magical, but if such was the case then why are they hidden from the muggles alongside everything that is actually magical? Just based on that, I lean towards their size and strength being magical byproducts so they wouldnât work with anti-magic genes either.
As for the question of when one stops having muggle genesâŚit depends on the specifics of how exactly the magical genes work. It would be nice to have some confirmation, but at least the way I understand the issue there is no separate âmuggleâ species, just humans with varying levels of magic-focused genes. Having all the basic magic-giving genes result in magical folk. Certain mixtures result in folk that are not inherently magical but can have magical children if their partner has a compatible mixture of such genes. And there are certain genes, most likely dominant ones based on Vernonâs description, that prevent any activation of magical genes if theyâre present at all. (So yes, if enough of such muggles are born they will eventually wipe out magic in humans unless safeguards are taken against that eventuality) Give these genes the right activation conditions and you end up with the mix of magical and non-magical folk within single families that we see in the series.
Iâve actually done a fair bot of research into this since a discussion on magical genes here on tumblr in like 2024 or something, I just havenât fully completed it since I got stuck on the best way for metamorphmagus genetics to work. Oops and all that!
