So, anti-endos, answer me this (really long post ahead by the way):
Why are you so hateful of non-traumagenic plurality, when the experience of being multiple goes back in history way further than the recognition of dissociative disorders? There are many religious and spiritual practices that have been around for a very long time that involve the existence of multiple entities in one body, or something similar to that.
Of course, just because dissociative disorders weren't recognized then doesn't mean they didn't exist, but my point is, non-traumagenic and nondisordered forms of plurality have existed in some way or another for a very long time. Saying that you can't be plural without trauma is erasing all of these religious and spiritual practices (and also invalidating plenty of other non-traumagenic and nondisordered plurals who exist for non-spiritual reasons as well, but I'll get back to that).
I've heard the argument that it's "just not scientifically possible to be multiple people in one body", but I don't think science supports the existence of a man who lives in the sky and created the whole world, either, and you don't tell people who believe in God that their religion is fake, do you? Let people believe whatever they want as long as they aren't harming anyone with it. Simply believing in a deity doesn't hurt anyone on its own, and neither does believing in the possibility of multiple people existing in one body. (I'm not saying plurality is inherently religious, nor that it's solely a belief, but it's a similar idea. Let people view the world however they like)
And just because there isn't a ton of science backing up endogenic and nondisordered plurality doesn't mean it can't possibly exist. Dissociative disorders are already under-researched, and other forms of plurality have been looked into even less in the scientific field. Just because a particular subject hasn't been researched very much doesn't mean it isn't real. Also, you can't possibly know what someone else is experiencing, so you don't have the authority to declare their own personal experiences false, because you literally cannot know that for sure. All you can know is what you do and don't experience, and no one else.
I've also heard some people say that the problem is endogenic and nondisordered plurals taking the term "system". Now, it may be true that the term was originally used for disordered systems, but you don't own words and I really don't see a problem with others calling themselves systems as well if it feels right. There's nothing wrong with wanting your own terms, of course, but I don't think the entire CDD community is as mad about this as the anti-endo side is. And now that the word system is being used more broadly, you can specify DID system, OSDD system, etc, and now you have your own term again.
And if non-CDD plurals using the term "system" is the problem, then... why do you still attack and fakeclaim plurals who don't use that word to describe themselves? If the word was the issue, then why be against endogenic plurals who don't call themselves systems? If it's because it's "not possible", well, refer to the paragraphs above. If it's because it's "harmful"... how? How is it harmful?
Is it because endogenics supposedly spread misinformation? If so, what information are they spreading that you think is false? If it's that you can be multiple people in one body and/or experience plurality without trauma, refer to the paragraphs above.
Is it because endogenics want to force plurality on people? If so, this is honestly just... not true. I'm sure there are some people who do that, and that is obviously not okay. But the majority of the endogenic and pro-endogenic community doesn't actually do this, and the fact that some may do that is not the fault of the entire community. And while plenty of us do encourage people to look into plurality or create headmates or the like, most if not all of the people who do this only suggest it if they think the person could benefit from it, and make sure to make it clear that it's not a choice to be made lightly and should have a lot of thought put into it. Rarely do we actually try to force people to be plural-- If it's not for them, it's not for them. And that's fine.
Is it because they encourage plurality, when it can be damaging to your mental health? If so, yes, it can be. But it isn't necessarily. It's not like they're encouraging people to self-harm, something that's always harmful, because plurality is not always harmful. It certainly can be an unpleasant or damaging experience, but for some people it's perfectly healthy.
Is it because they're appropriating DID as a "funny ha ha people in your head fun disorder"? If so, you do realize that... it's possible to have DID and not be completely miserable with it, right? It's the same for any disorder. People can learn to live with disorders, and I honestly don't think any disorder is pure misery 100% of the time. And for some, it can be difficult to deal with, but making light of it and trying to be positive may help them cope with it. Also, you see such a tiny fraction of people's lives on the internet. Just because someone is showing a positive aspect of their existence doesn't mean that's their whole existence. I don't have DID, but if I did I don't think I'd want to film and post a horrible, miserable dissociative episode to my social media, but that doesn't mean that said episode doesn't happen anyway. Also, we acknowledge that DID isn't just having alters. Yes, having alters doesn't mean you have DID. We know that. Most of the community is not claiming to have DID solely because of the presence of alters and alters alone.
Is it because they're faking a disorder? If so, first of all, how do you know that for sure? You simply can't, as I mentioned before. Second of all, if you'd take a second to actually read their profile or even just ask them, most endogenic systems aren't even saying that they have a disorder. How can you accuse someone of faking a disorder when they literally say they don't have said disorder and aren't claiming to?
Is it because they treat alters as separate people, which makes dissociation worse? If so, I'm sure it's true that for some, treating alters as their own people instead of parts of a single person can indeed make things worse. But that's not the case for everyone. For those who don't experience that, why are you policing how they identify themselves? If that's how they prefer it and it's not hurting them, just let them be multiple individual people, there is literally nothing wrong with it!!
Is it because they're "just roleplaying"? If so, who cares? Let them have fun. If they want to roleplay as being multiple people and call that plurality, it's literally fine. It's not appropriating anything if they're not claiming to have a dissociative disorder without actually having one, which they are likely not. If they are roleplaying DID or some other disorder without actually having it, that's not good of course. But again, how do you know for sure that they're faking it? All of the common "signs that someone is faking DID" are... all things that can occur in DID. Just because they're supposedly uncommon doesn't mean someone who has one or more of them is automatically faking.
Is it because it's bad for their mental health? If so, how do you know? Even if you're a psychologist or a registered therapist or psychiatrist or any other mental health professional, you're not their mental health professional. You can't dictate whether being plural is harmful to the mental health of someone on the internet the majority of whose life you do not know. Please leave deciding whether something is harming someone to the people whose actual job that is, especially if nothing they post shows any indication that they're in a bad state because of it. If you think they may be hurting themselves in some way and want to encourage them to get help, sure, fine. But don't try to bully them out of something potentially completely harmless. Again, you aren't their therapist, and doing this will probably only hurt them more. Believe it or not, being attacked, fakeclaimed, and bullied by strangers on the internet is very likely much more harmful than being plural.
If it's because they invade traumagenic and disordered systems' spaces... You may not like to hear this, but, uh. anti-endos kind of do that too. I've seen plenty of people go in the pro-endo tags, seek out endogenic systems and their supporters, and relentlessly tell them how fake and harmful they are and how they should kill themselves and how they're not actually plural and how they're hurting real systems and... you get the idea. I've gotten one such anon myself, and again, I can assure you that hurts people more than just being plural. And no, I'm not denying that endos never invade traumagenic and disordered systems' spaces. I'm sure this is a thing that does in fact happen. But... why is that a reason that simply being endogenic or plural without a dissociative disorder is harmful on its own? And how is that the fault of every endogenic and/or nondisordered system who has never done that? (And before you say that not all anti-endos do that either, I'm aware of that. I have respect for those of you who don't seek us out to bully us. Thanks for letting us exist and go about our lives, though I do still encourage you to challenge your views. I hope this post helps with that.)
I can't say this is in any way comprehensive-- there are plenty of things I didn't include here such as plenty of reasons why anti-endo rhetoric is ableist, discussion about endo plurals who do have dissociative disorders (to be clear, I support them and I do think it is possible), how traumagenic-only spaces often exclude and are hostile to mixed-origin systems, the claim that endos just don't remember their trauma, etc. But those are topics for another post, because this one is already really long and I don't really have much to say about those topics to be worth including here. If you want to hear more about those, plenty of others on this site have talked about them. I recommend reaching out to Kris of @.dhddmods, as they seem to know a lot about the topic.
I think that's all I had to say. Wow, that post ended up a lot longer than I thought it would. Hope this all makes sense. If you went into this post as an anti-endo and have reached this point with a changed mind, I'm glad I was able to help you see a different point of view; if you're still anti-endo, I encourage you to think about this for a little bit, and if you have any other rebuttals leave them in the replies and I'll try to respectfully debate them (however you're not likely to change my mind on the validity of endos and nondisordered plurals, and if you can't be respectful I will delete your replies). Either way, thanks for reading this far, I appreciate it. Have a nice rest of your week!
