Why? Because *by selecting a box on that form*, I am identifying as that thing. That's what identifying means!
So you can make your questions shorter, easier to understand, and harder for right-wing jerks to target with hateful rhetoric :)
@YumKimil not sure what you mean - 'identifies as' is equivalent to 'says is', that is, "I identified as a gamer on that form" means "I filled in the box that says I am a gamer". You could be a gamer and not identify that way on a form - not fill in the box - but that would be lying, however ethically positive.
@tindall kind of like how I'm a woman, I don't identify as one. The same goes with my indigenous heritage and my sexuality. I don't identify that way because that is who I am. You're a transwoman, biological male who identifies as a woman, so you conflate identity with material reality.
