DU is the short bus of the internet.
Its also the lunatic moonbat fringe of liberalism. They state it flat out in their rules: Who We Are: Democratic Underground is an online community for Democrats and other progressives. Members are expected to be generally supportive of progressive ideals, and to support Democratic candidates for political office. Democratic Underground is not affiliated with the Democratic Party, and comments posted here are not representative of the Democratic Party or its candidates.
You can and will be banned over there for being a conservative or posting anything contrary to their way of thinking. So much for open-minded progressivism. I've never seen a bigger bunch of fascists anywhere.
The above comment about iverglass had me rolling on the floor. You just haven't read enough of her stuff. She is a 100% whacko, moonbat, America hating, gun hating CANADIAN!!!! That's right she's a member of the frozen north trying to bring her version of utopia to a town near you.
