You might wanna re-read that. Because it sounds like you're saying because I'm not trans, I can't dislike J.K. Rowling.
No, I'm not trans. And no, I don't like her. I didn't like what she did before and when she came out as anti-trans, I thought that was right on-brand for all the dumb shit she did before.
You're attacking an ally for agreeing with you. Not sure what you're trying to accomplish here.
