People with intersex conditions still have a sex, and its male or female.
Its intresting you mention eugenics though, its deeply disturbing how young some children are when they are being sterilised.
I was/ am non gender conforming, and as an 80s child it was acceptable. I think the children being sterilised now are the next great scandal, and there are going to be an awful lot of lawsuits flying around.
Nor do I blame them, the brain is not fully mature until mid 20s, these children should not be making such huge decisions.
