You're welcome to wonder why or even if men and women are different.
Don't let me, or the 7.8 billionish people who seem to think so change your mind.
You might try reading other posters comments before coming up with some of the claptrap you post. I never said there were no differences between the genders. I agree that differences exist in the mental/psychological area that can't be adequately explained by societal factors. My disagreement is with your baldfaced claim, repeated again and again with no backing, that such differences are greater than the obvious physical differences.
Men and women have even starker differences in their minds, gender roles, socialization and emotional needs than they have physical differences
Eh... that's a pretty low bar. The physical differences are so small it's easy to imagine an alien race not being able to tell us apart male vs female. At least those certain kinds of fish and birds have crazy stuff like the female being 100x larger or the male having colorful feathers.
But how would such aliens then notice the "starker differences in their minds"?
