Intersex is two things :
-Physiology of mixed sexual organs as your sister-in-law's daughter
-Psychology as in a woman who uses right brain (transgender man) or a man who uses left brain (transgender woman)
Both cases are proven scientifically by gynaecology and psychiatry. I don't see any reason a woman would optionally aspire to live as a male or vice versa. It's an accident of birth. Particularly transgenders suffer gender dysphoria so they have no choice but to crossdress, hormone therapy, surgery, etc. A biological woman who think like a man will invariably get into brawls, drink tusker, dress as a tomboy and walk into gents or male toilet. Trouble become that they can't use urinal while standing
I don't know what motivates GeeMail to imagine this status as fun, optional or evil. Except that he is a tree-hugging hippie and a "conservative" - so everything must remain the same. Everyone needs proof except their imaginary Jesus.
Basically think of it as male,female and other. inter-sex are people who are neither male or female because of biology and physiology and because it's their right to be whatever they want.my wife sister recently discovered her daughter didn't have a vagina - she had a hole for peeing only - and they took her for surgery - I am not sure how she will turn out in the future.
We risk speaking at cross purposes. We need clear answers on:
What is "intersex"?
What is a "sex continuum"?
