At least OWS looks at real issues.
Exactly. OWS people are people who perceive the fundamental injustice of our modern societies and translate it into an incoherent outburst of rage. They are understandable, even though don't really help solving the problem. The teabaggers on the other hand are the pure product of a despicable reactionary propaganda with no connection to real life. They believe they are fighting against the establishment when, in fact, they are its useful idiots.
That and the OWS isn't merely a far left movement. In fact there are more than a few conservatives I know who are part of the movement because they believe that OWS is an anti-partisan movement protesting political corruption. To those who watch Faux News it probably seems like a bunch of communists and anti-capitalists or what not, but to those who actually research it there is a genuine anger within the movement.
Too bad OWS is too damn incoherent to really resonate with people.
