Sure, there is going to be hostile anti-Jewish feeling expressed at the margins of any populist movement, but a) it appears as if the people expressing these thoughts in the video are real outliers; b) it's obvious to me that most people who attend these rallies are angry about corporate greed and excessive CEO compensation (among other financial concerns) and not about Israel or perfidious Jews; and c) this movement has (like most political movements, actually) disproportionate Jewish representation. To say that there are occasional outbursts of anti-Semitism at Occupy Wall Street is not to say that Occupy Wall Street itself is antisemitic. The University of Chicago has an anti-Semitic professor on the faculty, but does this make the university itself anti-Semitic?
