Those who say they dislike dogma, or 'certainty', tend to be liars, hypocrites, or simply wrong. What they really dislike is the dogma of those they disagree with. A society that was certain, certain beyond all certainty, that putting its citizens in death camps was wrong, would never put people in death camps. Such things are only possible when you're open to new ideas.

The logical upshot of liberalism's hatred of hypocrisy is that it is better for the liar to champion lying, the glutton to advocate gluttony, the adulterer to celebrate adultery, than for someone to preach the right thing if he himself occasionally does the wrong thing. Better to let your failings define you and be happy about it, than to let your ideals define you but then fall short of them, for that opens you up to the charge of hypocrisy.

The mainstream perception that conservatives are close-minded and dogmatic while liberals are open-minded and free-thinking has it almost exactly backward. Liberal dogma is settled: The government should do good, where it can, whenever it can. That is President Obama's idea of pragmatism and bipartisanship: He's open to all ideas, from either side of the aisle, about how best to expand government and get the state more involved in our lives.

If you spend any time in Washington you'll find nerds. What happens is most of them sublimate their fixations with comics, or baseball cards, or 1960s British comedies to policy minutiae and political arcana. But, like Christians in ancient Rome, you can still spot them if you know the signals.

Social distinctions tend to matter only at your own level and above.

Look, I think liberals have reasonable gripes with Fox News. It does lean to the right, primarily in its opinion programming but also in its story selection (which is fine by me) and elsewhere. But it's worth remembering that Fox is less a bastion of ideological conservatism and more a populist, tabloidy network.

As a broad generalization, big businesses have no moral objections to being whores. Getting into bed with Uncle Sam is all a question of price, not principle.
