What is the species characteristic that is the basis for misogyny in human kind?

My girlfriend asked me this question at Starbucks this morning. She does this stuff all the time. It is why I love her. I have my own opinion, but it is a big question, so I thought I would invite you to join in.

It really does not matter the human time and place. It is a common theme.

And no religion, not even Buddhism (generally regarded as a sort of universally palatable mystical philosophy), is devoid of misogyny. Christians, Jews, Muslims, Buddhists etc all have themes of mistrust or even disdain for females in their doctrines.

But humans are human first, and religious creatures second. So it stands to reason that mysogyny is a human expression, not an institutional one.

It also seems reasonable that, given the choice, females would disapprove of such a notion.

So it clearly originates in the mind of males.

How did this all start. Is it valid. Is it morally correct. Or is it bullshit?
