Identity politics is a canard when it comes to Judaism. Being born Jewish says nothing about whether you care for Israel, because being a Jew is about more than emerging from a Jewish uterus. A secular humanist, born a Jew, is still a secular humanist. Noam Chomsky is a Jew, but he is also a twisted and evil thinker who pines for Israel's destruction. Tony Judt is a Jew, but he hopes that one day Israel will be wiped from the map. Are Chomsky and Judt immune from criticism because they are Jews?
They are not. Neither are Colmes, Kaufman and Dorchen. And none of them have the right to use their Jewish birth as a shield for their anti-Israel and often anti-Semitic views. Identity as a Jew is important in this debate only when that identity means a binding tie to the Jewish nation as a whole and to the God that bound that nation together at Sinai.
The believing Jew is tied to Israel because God gave the land of Israel to the Jewish people; the believing Jew is tied to strong Israeli self-defense because God mandated such self-defense in the Torah. A Jew who believes in his religion may without question claim that his Judaism demonstrates his commitment to Israel. It is a foul and rank political convenience for those who care nothing about Judaism to flout their Jewish birth as some kind of defense for their cowardly and foolish surrender-first ideals.
