Fair enough. Female porn preferences probably reveal something about female sexual desire, and probably quite a lot, but I accept that it's complicated.
But anyway, I'm no longer going to debate the fact that, generally speaking, women are sexually attracted by male dominance/ status/ power. It's like debating whether the world is round.
Instead, we should be asking why people like Roosh are so unhappy with this fact.
I think it's because they find it unpleasant to accept that female sexuality is just as amoral as their own. They prefer to think of women as basically asexual, and wish that women would be sexually attracted to men on the basis of their "niceness." When they discover, thanks to feminism, that women are in fact just as amoral as themselves when it comes to sexual attraction, their heads explode.
