It works if one entirely disregards biological sex, I suppose? If one posits everything based on 'gender identity'.
But how is this related to sex at all, in that case?
'Gender identity' is personality, nothing to do with sex, body, or biology. It's feelings and thoughts and ideas, yes?
I can certainly grasp that people don't feel that socially constructed gender stereotypes don't accord with their internal sense of self.
Because OF COURSE invented and arbitrary 'gender' stereotypes don't chime with internal feelings.
My body is sexed, I experience life as a woman every day, all my life. Always will.
But nobody has an 'innate' feeling of their sex. Or at least, if they did, there would be absolutely no way whatsoever of knowing, because we cannot experience outside of our own experience.
We can make guesses, which may be more or less informed or accurate, based on observation, assumption, and the say-so of others, but we simply cannot know what it is like to be the opposite sex, or to be other than the sex we are born. It's quite literally impossible. Totally and utterly.
