On the comparatively rare occasion that a conservative of some sort is invited to speak on a college campus, leftists of various stripes come out not just to protest, but to silence the opposition. They take over the stage with yelling, shouting and the occasional assault in an effort to maintain the ideological purity of the campus environment.

I noted last week that actor Sean Penn had endorsed Dennis Kucinich. Below is video of that announcement, complete with a demonstration by a San Francisco State University college Republican on how to respectfully protest.

The other bit of good news is that, when a couple of Kucinich supporters go to assault him, the campus cop knows which one to arrest. (via Little Green Footballs)
