Check out Freakonomics’ Stephen J. Dubner on the fair-minded liberal Nick Kristof, and don’t miss this special quote from some other guy at the end:
People have often said that politics has been the religion of the 20th century, and I think there’s a lot to that. In the same way that people get attached to a religion, they get attached to a political party. And once you’re part of it, you don’t want to hear someone talking about the horrible things that your religion or your party did in the past. You don’t want to go and say the people who now run it might be morally questionable, or hypocritical, or just wrong. Instead, you want to find a sense of community with a bunch of like-minded people. You all tell each other how wonderful you are and try to defeat your Satanic enemies who for some strange reason continue to dispute the truth that you have obtained.
