Yeah, I know exactly what you are talking about. And Mike, It's true that most groups have these kind of people. But from what I've experienced, At MSU, is that most liberals are like this. Maybe the laid back, Think before they talk, People just don't get a Chance to say anything because the "liberal" can't shut his mouth. But, I do know more that are the Sterotypical Liberal then a Laid back one.
I saw this as a Bumper sticker once:
"Liberal - A person so open minded that thier brain has fallen out"
