I think women generally don't like football because it is too difficult to understand for them and they can't grasp how points are awarded. Versus baseball which is clearer on how to win the game and every runner in equals one point. Plus, I think few women can listen to a sports game on the radio and know what is going on.
Yeah, you may be an exception, but c'mon - women do better watching things like figure skating and synchronized swimming which, IMHO, aren't even sports. They're just thinly disguised dancing, albeit in a unique environment. Which blows.
