You can hate on Joanne without being trans because she’s a terrible human being that put Jewish stereotypes in her books, made slave owning the normal and the people going against it the ridiculed minority.
She also made the jock main character that won sports because he always got the newest most expensive broom instead of hard work with rich parents a cop. Also she keeps retconning stupid stuff like how wizards just poop on the floor and magic the shit away.
On top of that she’s a TERF and just a giant shit stain on society that wizards should just magic away.
Imagine the only way to regret putting something made by a terrible human being on your body is to be directly affected by it. Imagine having empathy.
I’ve looked a bit into the past of this community and there’s quite a bunch of open source projects shared here and none of them had people in the comments complaining about that. Honestly just seems like thinly veiled queer hate to me.
