The BIGGEST difference between OWS and the Tea Baggers is that OWS isn't completely sponsored and directed by the Koch brothers, Dick Armey, et al.
The other lie the right is spreading is the anti-semitism. At least in NYC, that is completely untrue. My brother is a policeman, as are many of the officers AND OWS protestors. Whenever some of the peace groups try to spout anti Israel crap, the OWS organisers quash it; trust me, the Jewish members and cops are going to stomp anyone having a HitlerJugend rally. My brother and friends have all TO A MAN said that the only anti semitic signs they've seen have been LaRouchies, Alex Jonesies, and Ron Paulists - and the usual nutjobs. They're escorted out of the park immediately.
As for it not having any affect - already the banks which where going to charge fees for debit card usage have announced they are stopping; the Democratic Party is reeling - they were heading further and further to the right, now their base is calling them on it and they're having to stop running to the right.
Whether you agree with what they say or not, they are well within their rights to protest - that IS in the Constitution... something tells me the Founding Fathers didn't have permits in mind when they wrote about freedom of assembly, etc. Can't see a Crown Governor issuing those.
