You could not take a male child and raise that child the same way you would a girl and expect the same person at the end, they would no doubt suffer severe problems from that.
A few months ago, I watched an interesting documentary on public television called "Sex: Unknown" (a Nova documentary, I think) about a fairly now well-known case of Canadian twin boys. Both underwent circumcision, however with one of the boys, something went wrong and the penis irrepairably harmed.
After consulting with physicians and psychologists, the parents chose to surgically turn the baby into a girl and to raise "him" as their daughter.
While it was a tragic situation, the case was closely watched by the scientific community because as the situation involved identical twins (genetically identical) it provided an opportunity to see what role nature and nurture plays in determining gender identity.
Well, for the boy who was raised as a girl, things did not turn out well. He never felt like a girl. He had an incredibly unhappy childhood. He was plagued by psychological difficulties.
At the age of 14, his parents revealed the truth. He rejected his female identity and chose to live as a boy. He actually has his genitalia reconstructed and is married with children.
Cases like this prove there are inherent biological differences between men and women that shape gender identity.
