In order to be welcomed as a Jew in a growing number of progressive groups, you have to disavow a list of things that grows longer every day. Whereas once it was enough to criticize Israeli government policy, specifically its treatment of Palestinians, now Israel’s very existence must be denounced. Whereas once it was enough to forswear the Jewish Defense League, now the very idea of Jewish power must be abjured. Whereas once Jewish success had to be explained, now it has to be apologized for. Whereas once only Israel’s government was demonized, now it is the Jewish movement for self-determination itself.
