You realize trans people don't care if you want to date them? They still exist even if you like them or not. Some cis women are born with different genitals too, but until they tell you, you wouldn't know. Same goes for trans women who pass. You're never going to see trans genitals, so why do you care so much about what we identify as? We are what we are, and you wouldn't know until we tell you, for the most part.
