I don't have a complete answer to Jackie's important question -- although I'll find out more about the group promoting this campaign.
About a week ago I saw one anti-Semitic sign being held up by a guy, and right next to him was a woman with a hand-written sign obviously written for the occasion with an arrow pointing at him and saying "He doesn't represent OWS." I thought that was a comradely, proactive start.
Of course at pro-Palestine demos when we see antiSemitic signs we remove the offender (with numbers, not laying hands on), and there's no room for debate about it OWS probably isn't at that stage of marshaling.

keep moving in the right direct with transparency and integrity. Haters are going to hate.
