the "nail on the head" article is a bunch of nonsense. I see very little connection at all with "OWS" and communism. And certainly anyone with a grasp of history knows that Stalin and Mao's tyranny had very little to do with Marxism.
OWS,IMHO, is about equality and fairness of opportunity. That is a position where liberals and conservatives agree, right? If OWS targeted the corrupt bastards running the Federal government we'd be right there with them. I think that will happen soon enough.
