I've always found that a very interesting thing. I don't think it has as much to do with the guy being a jerk, as it does finding a mate who fulfills a desired role. Way too many people confuse being an absolute asshole with being an assertive, supportive, adoring mate who is protective without being possessive. An "alpha male" is simply the male with the highest rank, and what elevates one to high rank in society varies from what it used to, at least to some extent.
What's really awesome is having someone around who's comfortable in their own skin, really comfortable with your skin, able to support themselves, willing to support you if you can't anymore, helpful in forming a safe haven from all the other idiocy in the world, and with the drive to pursue their dreams without abandoning all their other responsibilities.
