Interesting paragraph to ponder

From Tyler Cowen:

Here in the United States, one thing that strikes me about my most liberal friends is how conservative their thinking is at a personal level. For their own children, and in talking about specific other people [TC: especially in the blogosphere!], they passionately stress individual responsibility. It is only when discussing public policy that they favor collectivism. The tension between their personal views and their political opinions is fascinating to observe. I would not be surprised to find that my friends' attachment to liberal politics is tenuous, and that some major event could cause a rapid, widespread shift toward a more conservative position.
