Yeah it happened to friends of mine, well I stopped being friends with them back then because I was a terrible person. I had lots of dumb transphobic explanations for why they “switched sides” but really looking back with what I know now. It’s as simple as, anyone who “wants” to be trans just is trans. If they have a lot of transphobic prejudice they may go forward to “prove” it’s a choice but they’ll learn quickly that it isn’t, once they’re hit with the euphoria, or the dysphoria, or both. That’s when it becomes apparent how little of a choice it is.
