Another Voice in Support of my Theory

I'm catching up on some older posts in my RSS feed. Here's Kevin Drum chiming in on George Packer's bit in the New Yorker.

Drum says it better than I:

The big difference between right and left, as I and others have noted repeatedly, isn't just in the amount of violent rhetoric, but its source. On the liberal side, it only occasionally comes from movement leaders. On the right, it regularly does. It comes from opinion leaders, political leaders, and media leaders, and the more heated they get, the more popular they get.
