Actually, there is a difference.
I don't believe George Bush is an asshole because he's a conservative. He's just an asshole. If he were a liberal, he'd still be an asshole.
Face it TB, you're not going to make people who disagree with you go away, or change their minds, by reminding them every day how wrong they are. In fact, you will have just the opposite effect, you will turn people who have political opinions but rarely act on them into activists against you and your cause, and you will alienate moderates and force them into the other camp.
