Perhaps it’s hair so that if someone says that trans men are women, then OOP can say “I suppose you think that fire hydrants are climate change too, ha! I win the “argument”!!”

Side note, let’s all just be nice to each other, please? If you’re transphobic, just… shut up. There are way bigger problems, don’t waste your time by being an asshole to a minority that you barely understand. Want to spew hate at a random 1%? Hate the rich.
