This dude is saying what all the other Libbos are thinking.
He's a jackass who's just playing it up for the media. Before a few weeks ago, nobody gave a **** about this guy. He says something inflammatory and sees that he gets heralded as a hero among the fringe left. Then, the next day, he says something even more inflammatory and follows it up with a post on dailykos 45 minutes later raging against Republicans and begging for money.
He's basically followed that pattern since then.
People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf.
