This is already over and I'm not Directly involved* but I also think it's prob important to mention that the full extend of JK Rowling's transphobia is really often EXTREMELY downplayed. Transphobia is a form of bigotry not treated with a lot of seriousness and very flagrant and often violent displays of transphobia are seen as "acceptable" or "normal" by enough people (moreso than a lot of other forms of bigotry I would argue; I seriously think "famous children's book author thinks homosexuality is a mental illness on par with pedophilia" would be treated WAY more seriously than "famous children's book author thinks transgenderism is a mental illness on par with pedophilia" because most people literally do think being trans is a mental illness) for JKR's transphobia to be reported on mostly as "the trans community Disagrees with some of JK Rowling's statements" in its most neutral state and "can you believe the crazy pronoun mob is trying to CANCEL Harry Potter just because of a GENERATIONAL DIVIDE?" in its most nefarious. The idea that JK Rowling "just said a few things wrong and didn't use totally up-to-date language" is STILL how most cis gays especially above a certain age think about "the JK Rowling drama". The actual reality, which is that JK Rowling has spent years and years of her life not only donating to anti-trans orgs, not only publishing thinkpieces about irreversible damage and tomboy extinction and rapists in women's bathrooms, but spending basically every day on Twitter arguing with pro-trans tweets with literally three views (not likes, views), just is not reported on by mainstream media outlets. Cis people continue to treat "the JK Rowling discourse" as crazy triggered snowflakes blowing a few out-of-context comments made years ago out of proportion because they hate Harry Potter/women/family values/etc., and not more akin to the "Kanye West said he loves Hitler and somehow basically nothing has happened to his career" type situation it actually is. I just don't know how "canceled" someone really is if they still own a fucking theme park. I feel confident in saying that there is not a single trans person on this Earth who is as influential and successful as JK Rowling continues to be.
TL;DR millennials and older still manage to "not know" about JK Rowling (and by extension Harry Potter, because unlike most other "canceled authors" JK Rowling has outright said that she considers any and all mildly positive engagement with her work to be a signal of support of her ideas about trans people; I need to emphasize that this is Not Common and also not the actions of someone who got taken out of context by the crazy woke mob) because transphobia is so undervalued as an actual serious force of bigotry that mainstream media does not report on JK Rowling as a very serious and devoted bigot, in perhaps the most extreme example of "only trans people are expected to care about and notice that this is happening"
