I don't hate the Cowgirls, I just dislike any pro team that is/was way over hyped, over paid, has annoying owners, buys everything they can in an attempt to win, etc. So I also dislike the Yankees much more than I dislike the Cowboys. Blame it on the media, they're the ones that overhype "America's Team"!
Oh, I still love the fact that the Beagles haven't won a super bowl either. Philadelphia media is painfull to listen to as well. The Giants have managed to win a couple of Superbowls and they never had a dominant team and that's what I find fun to watch.
