TBH I still don't get it.
Your biology and psychology are so entertained they cannot be analysed separately.
The vast majority of people are born one sex or the other.
There is no 'gender' apart from that imposed by society.
So if you are born a man - why declare you are a woman? Surely it makes more sense to widen the gender construct of maleness?
It seems illogical to argue you are born 'male' but that doesn't fit your 'female' mind (the one that likes wearing high heels and being 'one of the girls' whatever that means)
