Do you mean that, because women are capable of carrying a child to term that they are more interested in copulating?
Do you mean to say that women want to have and raise children more than men?
I'm not sure I understand your point.
As to "Women are also just different than men in some way, not just physically, but socially", all I can say is this was much more true 50 years ago than it is today, but that doesn't mean that it's not true now. What I (as well as the author of the article) was trying to address is: Why?
"We should close gender gap where possible, but we shouldn't insist on equal gender balance if women really don't like to go into the same career that men goes into."
Who is advocating forcing people to do things?
