Pretty sure our fucked up environment is the cause of most trans people actually and have not always existed. There are so many plastic contaminants that mimic estrogen ( and other things we don’t know), look up the effects of Atrazine (common insecticide), that shit made fish and frogs grow ovum in the testicles (no I don’t subscribe to the frogs are gay fuckhead)

Regardless, dress how ya want, do what you want. But plz don’t freak out on people who are not closely tied to the LGBT community about your gender when we don’t know/don’t care.

I’m sorry you have deal with uneducated bigots, I know the feeling, although my life was never threatened as an obese child/young adult, regardless the mental outcome is the same.
