Liberals Love Violence. But Why?

We have seen, over and over, how liberals are attracted to violence. Not real violence, necessarily: there, liberals tend to get the short end of the stick. But threats of violence, idle talk about violence, liberals love. Bill Jacobson has the latest from Wisconsin, where liberals yearn for someone to kill Scott Walker:

Professor Jacobson asks, reasonably: Why do these people, many of whom are professionals, feel no fear in expressing such death wishes in the open?
I think the answer is that as liberals, they assume they are immune from scrutiny. Glenn Reynolds agrees: “They’ve lived for years in a culture of impunity. But that’s changing faster than they realize.” Maybe. But I don’t think it’s changing fast enough.
