Buck Angel is a tranny pornstar who has spent pretty much his entire life advocating for and supporting transpeople and being a widely recognised trans figurehead, but then one day he started calling out predators and criminals in the trans advocacy community and questioning whether or not it's a good idea to drug and mutilate confused children, so now he's basically worse than Hitler.
Incidentally, for all the credit we take for exposing the TransLifeLine charity fraud, he's the only reason the directors ever got ousted for it.
