A problem OWS had too is that it was rather vague. It didn't have a concrete demand to organize around, but a populist "we are the 99%." Effective at growing rapidly but also prone to these "multi-issue" problems where the fruitcakes start showing up and saying that everyone must bow down before a disabled Navajo lesbian (I'm trying to come up with something really stereotypical). Also conspiracy theorists and other crackpots. At the time, the biggest line of attack from the corporate media was "we don't know what they're protesting for." It's like saying you're against "greed." Any bourgeois politician can also say they are against greed.

The difference within the anti-war protests during the Vietnam War was to say "troops out now" (that could happen) and "end imperialism," but even Nixon could say he was against imperialism. He was against Soviet imperialism! Or, America isn't imperialist, what are you talking about, that was the British and the French and of course we're against that.
