I think it should be considered a form of degendering to try to divorce trans people from their gendered histories. My gender doesn't make sense without the fact that I was a little boy, or something like it, before I was a girl and a woman. If you were always a girl, thats awesome, but a lot of people project their dysphoria onto me when I try to talk about my own fucking life. If you think talking about having been a boy makes me less of a woman, that is degendering.
