I'm a gay detransitioner who stopped taking hormones simply because I ended up not liking the idea of being on hormones and getting surgery. My insecurities aren't gone, but there's been some freedom in not being nervous about the increase of cardiovascular issues from hormones. I was also aware of Rowling's comments and never thought of her as being against trans people.
Over the past few weeks though, I paid attention to a lot of the people following her on Twitter who support her most, and I noticed that a large amount of them don't agree with a single thing Rowling has said about trans people. Rowling is on record for saying that she has no problem calling trans men he/trans women she, supporting adults having fairly easy access to hormones/surgery, saying that she considers most trans people 'vulnerable' and even saying she knew a trans woman that she could barely see as anything other than a woman. In contrast, a lot of 'gender critical' people say the opposite of those things. They get triggered by the idea of calling a trans woman a she and vice versa, sometimes don't even use their legal names, mock their appearances, think that trans people don't have their own specific needs, and in some cases, saying that the mere concept of being transgender is a capitalistic 'white male' misogynistic scam that manipulates mentally ill people, and that even adults shouldn't be allowed to transition. You can deny it if you want, but I can safely say I have seen all of these things said in 'gender critical' Twitter and forums. The word disingenuous doesn't really cover the attitudes of people who say that the whole concept of being trans is bad, bigoted and a capitalist scam, while simultaneously saying "We aren't anti trans". I am fully against gender ideology, but seeing these people's sentiments made me realize they don't really agree with what Rowling has said.
