I am drawn to Chomsky, intellectually. Yet I find actually attempting to consume his intellectual production, in either linguistics or in ideology (politics), extremely annoying. He's an annoying, self-righteous narcissist. But an undeniable genius.
There's a very interesting interview with him, recently published at Tablet. It focuses on his specifically Jewish identity raised as a "cultural Zionist."
In conclusion, though… he's not a moral relativist: "You can’t get out of your skin. But when we get down to the moral issue, it’s independent of one’s personal background."
