I really liked a comment on this post by Will at Patriactionary left by a guy who called himself fitzhamilton (the post itself is very funny, btw:).
I can't figure if it's possible to link to it directly, so you'll have to follow the link above and then scroll down to read it in its entirety, but here is a quote:
Men generally tend to the exception in at least one area, women to general mediocrity.
This is why women form collectivist hives, and men form meritocratic hierarchies. Women don’t belong in public life, they belong in the home and community doing the three things they far excel men at: taking care of children, their husbands and maintaining the hearth and intimate interpersonal relation vital to local community.
