> a man who believes he is a woman is not in any recognisable sense actually a woman. You are talking about someone whose biological sex at birth was male, and whose gender is female. In other words, you're confusing biological characteristics with gender. Gender refers to self-identity, cultural behavior, and presentation. The World Health Organization[1] and the Oxford English Dictionary[2] have accepted this definition. On Facebook, users may fill a freeform gender field (not a dropdown) and select a preferred prounoun. Users are not required to substantiate gender, nor would there be a way to. Notably, Facebook never asks anyone to give medical info about their biological sex. Neither should you.
