Self identification is a ridiculous concept if it's not based on fact. They put people in the nut house for proclaiming they're a farm animal or Teddy Roosevelt.
Actually, It's called not knowing what the fuck you're talking about
The logical thing to do would be to educate yourself.
P.S. trans people's brains objectively show non expected neural activation. And this is just one of the many ways for people to understand trans. It's a real thing and you need to EDUCATE YOURSELF instead of acting like bill oreilly. Ignorant asshole.
