There was a famous feminist in the 70's (forgive me for not remembering her name, I was born in the 80's and this is just what I've read) who wrote a diatribe about how transwomen were basically committing rape by appropriating the female form without having gone through female hardship.
And the most hurtful flak I've gotten as a transman has come from feminist friends. Some of them see what I'm doing as betrayal, and as a decision. To some of them it looks like I'm just caving to male superiority and trying to get ahead any way I can. That's not true. I'm just incorrectly gendered, and any political implications are just happenstance.
I still consider myself a feminist, whether other feminists accept me or not. Even if I am a man, I'm not going to stop recognizing the gender inequality that exists.
Lol they hat us all.
