He's saying that even if they don't support Israel, they still support a bunch of other draconian and/or debased stuff. He isn't wrong, even the Jewish rabbis who think Israel shouldn't exist until the Messiah comes are super sexist and racist. They just protest against Israel and so you think they may be good.

I think a good Jew is a Jew who does everything in his power to separate himself from that evil cult. How many do you know who have done this? Not even Norman Finklestien, super out-spoken supporter of Palestine, even Norman supports lies and debased culture (through fools like Chomsky)
