http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=104&topic_id=3964904&mesg_id=3964904I believe that, as Plaid Adder said, popular applications of evolutionary biology are more insidious than even religion when it comes to reinforcing the gender roles that a lot of institutions have a vested interest in maintaining. Religion, despite the persistence of fundamentalism in various corners, is losing it's grip on the human imagination. Therefore something had to take it's place, and quick, to ensure a steady supply of babies to be consumers and cannon fodder.
That something is what I like to call Discovery Channel Bullshit. It's got the imprimatur of "science" on it, so it can be used to keep people entrenched in prescribed gender roles. After all, you don't want to be "unnatural" do you? Woe unto you if you are the hapless female who likes promiscuous sex or the male who is monogamously relationship-oriented. Or if you are gay. You are a deviant freak, just as you were a sinner when religion imposed the rules. It's also, as we all know, frequently used to derail and dismiss feminist arguments.
It's not that I think studies of animal and human behavior purporting to show evolutionary basis have no merit. Not at all. I just take them with a big grain of salt, because there is often an ulterior motive.
