This analysis really helps! Recently I got into a comment war with a guy, who claimed that jk Rawling wasn’t transphobic (facepalm emoji here). When I showed him that according to the dictionary she meets the criteria of being transphobic, he explained she wasn’t actually afraid of trans people, but rather afraid of fake trans people. As in people who are just pretending to be trans and aren’t really. He explained since we don’t have effective enough tests to separate the fakers from the real trans people there’s no way to tell who is “authentically trans” and all of her fears were aimed at “fake trans” people not actual trans people. He also kept trying to change the subject by brining puberty blockers, and just like insulting me. Now I realize that again he is just using this technique of debating the trans experience.

I have heard of detransitioners who explained they realized they weren’t actually trans. There may exist people who aren’t actually trans but believed they were. To that, I think all people should have the right to transition and detransition as much as they damn well please without their actions being used against a whole community of people. Plenty of people get breast implants, then later get them removed, should we ban everyone from getting breast implants because some regret their choices?
People should be allowed their live choices and agency over their own bodies without their actions being used to deny others healthcare.
And saying a person only hates “fake trans” people, but then saying there’s no way to distinguish “fake trans” from “real trans” is like if saying they hate all trans because you can’t really distinguish between the two. I now know how to classify these arguments. It helps.
