Everytime I see posts like this, it's hard not to think OP isn't just trolling or are just also bigoted and that's why they don't see an issue with it...

Maybe your problem is you just keep asking social media users instead of reading one of the many, many articles outlining it.

She might not openly say bigoted things, but it's pretty obvious she holds bigoted views. Like, someone can be bigoted even if they don't admit it.

What did she say?

She believes that people born as male will always be male and people born as female will always be female. She doesn't mind if someone born male wants to dress up like a woman or if someone born female wants to dress up like a man, but that's all it is. Dress up. You can't change your gender. It will always he the same as the biological sex you were assigned at birth.

Those beliefs don't sound all that bad at first, but here's a personal story. When my brother was younger he was into metal. He grew out his hair, painted his nails, wore bracelets and necklaces. He was also a bit chunky so had some man boobs. He frequently was addressed as "miss", "mam", "she", "her". My brother would correct the person and they'd immediately apologize and begin referring to him with male pronouns.

My brother isn't trans. He was born male and wants to be addressed as a male. What if, when he corrected the people who misgendered him, they didn't apologize. What if instead they continued to call him a lady because he had long hair and painted nails? What if they requested to see his penis or birth certificate to prove he is actually male before they address him as such? Those people would be assholes, right? Well J.K. Rowling is one of those people.

Happy to help. :)

Extremely rarely do racists, homophobes, transphobes, and the like specifically say "I hate x," because then it gets harder to rationalize that away both to yourself and others.

That said, yes, she has. Lots of claiming being trans isn't a legitimate identity. Referring to trans women as "trans identifying men." Wrote a literal novel about trans women being serial killers, sniffing panties and hanging out in bathrooms to claim their next victims. Trying to speak for cis lesbians and claiming trans women are especially dangerous to them, despite cis lesbians being one of the least transphobic demographics and not being a lesbian herself. Retweeting hateful statements from even more blatant transphobes. Oh and I nearly forgot, straight up taking the label "TERF" and wearing it like it's somehow a badge of pride.

I know you said you don't want to watch some super long youtube video about it but I'm going to link to two of them anyway; it's a complex topic! They're pretty funny and come from the perspective of a trans woman with a background in academia. This one is pretty recent and comes with the added bonus of teaching you a lot about the history of social justice in general, and the fight for LGBT rights in particular. This one is older but is more focused on Rowling. Just keep in mind she's done much worse since that video came out.

A lot of what she says is purposefully dogwhistle-y, but she does like to equate trans-women with rapists a lot. She also actively funds anti-trans organizations and been outspoken that trans-women are not women, which is inherently hateful.

This is a Vox article recording her transphobic actions over the years

EDIT: Hit send before I was done typing.

EDIT 2: I think OP is purposely pot-stirring and looking for a 'gotcha'. This is probably a violation of rule 5

There's a Vox article that goes into the issue pretty deeply.

They are long articles because there is quite a bit of different things that indicate how much of a bigot she is.

Do you want her to wear a Klan robe before it's "overt" enough? That's not how the world works.

People who menstruate.’ I’m sure there used to be a word for those people. Someone help me out. Wumben? Wimpund? Woomud?

For starters…

Upvoted for the dumpster fire

Edit: Sorry, this is no stupid questions, I shouldn’t be joking around like that. It’s just that if you really haven’t read anything she’s publicly said, okay. But it’s pretty well known what her stance is on those and other topics. In my opinion her views are not aligned with inclusivity or empathy. We don’t know her in person, all I can judge is her public persona.

Quick web search flushed this up.

The common reply i get when i point this out is "she associates with known transphobes", which is pretty weak. Reality is she's not transphobic or hateful at all, but i'm about to be downvoted to oblivion for this, and possibly you too for even asking

No, lol. She said that there are two sexes, men and women. Which is true. She also said that women are being attacked in their own locker rooms by men pretending to be women, which is also true.
