The vast majority of the world see and man or a woman. Gender seems to be important to people who want to be different to what they are, be that a man or a woman. There are of course medical exceptions, a middle ground if you like, but fact is genders have only really been a discussion in the social age. 40 years ago no one outside of a handful of people even considered them really. It was blokes and birds, the mental state you allude to was never discussed in my childhood, it has become an elevated element for a certain set of the current generation in the main.
I make no judgement, live and let live.
