Really now... Picking on one or two isolated incidents.. (The spitting and crapping).

Aren't you guilty of doing the same thing that you complain about when people argue that the Tea Party is made up of racist bigots because a few of THEM showed up at the rallies?

Yeah, there are plewnty of more substantial differences - though the arrests are almost entirely for trespassing and I suppose that's one way of sticking to your principles (as opposed to the old anarchist demonstrations of bashing in shop windows and other acts of vandalism).
