You'll be able to easily find a number of anti-Trans stuff from her.

Things like her moaning about a university not granting the screening of a pseudoscientific anti-Trans film

Or her coming out in support of someone who was removed from a think tank for being publicly transphobic

She has peddled a conspiracy theory that doctors are trying to push kids into taking hormone replacement therapy.

She's close friends with anti-Trans activists like Helen Joyce, someone who actively called for a "reduction" of the amount of trans people. To me, calling for a "reduction" in the numbers of some minority group immediately raises alarm bells in my mind.

She has retweeted anti-gay, anti-Trans activists like Caroline Farrow.

She wrote a book involving a trans character where she detailed that the character was unable to pass. The main character 'hero' of her book gleefully threatens prison rape for this trans woman.

She pedalled the debunked "fact" that trans women are a danger in women's toilets.

She liked a tweet that said trans women are just men in dresses, and that calling them women is misogynistic.

She liked a tweet saying trans women are inherently sexual predators, saying they're like "foxes in a henhouse, identifying as hens" - in the interest of being transparent, I will say she unliked the tweet after receiving backlash, alleging she liked it by accident. I'll let you be the judge on that.

She wrote another book, Troubled Blood in which the villain preys upon women by dressing up in women's clothes. Pretty clear what she's alluding to there.

In an interview, she states that "90% of HP fans agree with her stances on trans people" and that they're just afraid to say so because of the violent trans mob.

She purposely doxxed a trans woman, who then received a bunch of death threats.

She compared the acceptance from the state that trans people are real to 1984 - "War is Peace. Freedom is Slavery. Ignorance is Strength. The Penised Individual Who Raped You Is a Woman.”

She wrote another book, The Ink Black Heart, where there is a stand-in character that is clearly meant to be Rowling herself. In the book, the anti-Trans activist main character is "cancelled" online, and is then killed based on trumped-up charges of transphobia.

Rowling opens a domestic violence help centre that explicitly bans trans women, despite trans women being disproportionately likely to experience domestic and sexual violence.

She said she finds it amusing people have lost respect for her because she "doesn't support violent, duplicitous rapists" - i.e. trans women.

This woman is a fucking billionaire. If I had that kind of money I'd be sipping drinks on beaches, going rock climbing, banging expensive prostitutes, and putting money into good causes.

What does Rowling do? She takes the one thing she can't buy - time - and spends it on stirring up hatred for a minority group. She is awful.

And it's a real shame. I still have my first edition collection of HP books, and I like them, but she certainly takes some of the shine away from them.

ContraPoints has a video that explains a lot of it: https://youtu.be/7gDKbT_l2us?si=_RQR_ZJE2ZHsh8E2
