Copy/paste from the main post:
People who are part of the Fediverse are generally progressive, which is why they are here to begin with instead of facebook/Xitter/reddit.
People who are progressive generally don't like people who don't like trans people.
This is just anecdotally, but it there seems to be much higher than average rate of trans persons on the fediverse.
I disagree with separating art from artist.
JKRowling is a transphobe, and continuing to support harry potter directly supports said transphobe
Lemmy is VERY left leaning overall, and also still very small. You're just not going to find enough people here to populate an entire instance based around the terf's book series. Moreover, why would you even need an entire instance dedicated around one fandom? I'm still confused as fuck that Star trek has multiple dedicated instances.
Additionally, putting the terf aspect aside, the Harry Potter fandom just isn't what it used to be. Cursed child was garbage, Fantastic Beasts were garbage... and that's all there's been in recent memory besides "Wizards used to shit themselves". The last HP movie was 12 years ago, the last actual book 16-17ish years ago. The fandom is moving on.
That all being said, this IS Lemmy. Absolutely nothing is stopping you from starting a Harry Potter instance.
Moreover, why would you even need an entire instance dedicated around one fandom?
startrek.website has entered the chat.
That said, it's telling that there isn't a Star Wars or Marvel one (yet), despite them being equally large franchises.
The current demographic like fantasy in general I suspect, but are less fanatic about the books, pop culture, merchandise or even fanfiction aspects of the Harry Potter franchise.
