I suggest you read the Biology and Brain sections of the wiki article on gender (also quoted in my above post). It appears to be an indisputable fact that there is at least some biological sex-related differences in psychology, brain function, and personality between male and female homo-sapiens.
Shame on you FusionKnight. Calling something indisputable is careless

What we the scientific community believes to be true is that the structure of the human brain differs somewhat depending on sex. You can't tie psychology and personality directly to that kind of genetic statement because we aren't certain that those things are caused by genetics. That being said, obviously brain function has a role in each, and should be easier to look at with regards to genetics.
What we need to determine is what hormones actually do to the brain rather than simply apply them to our traditional gender roles in the form of educated guesses. So we know that men have more testosterone in their system than women and that we believe the net effect that is important is increased aggressiveness. The psychological effects of estrogen appear to be predominantly physical, or defined as the opposite of having large amounts of testosterone.
So I can understand why an average increased aggressiveness in one sex would tend towards things like patriarchy, but the other two mentioned commonalities I believe have non-genetic causes. Romantic love and sexual jealousy are entirely too easily caused by a combination of cultural norms and evolutionary preference (romantic love between couples other than male and female do not lead to the continuation of the traits of those individuals and neither are males who are not angered by being cut out of developing progeny by competition).
So aggressiveness describes how one sex can achieve patriarchy, but I haven't heard an argument as to why that is an especially desirable trait to have in a leader. Maybe you can help me out with that.
Oh, and as a side note, I believe I understand your position, think it has merit, but disagree.
