When he does the "anti-semitic/ racist shtick" he seems to be making fun of the anti-semites and racists. That's how I take it. And he is funny, and he is smart.
However, in general, I don't tolerate hollywood, and that includes him.
He would have earned my respect if he, rather than standing in the middle of the rodeo grounds while singing his "kazakh anthem" or whatever it was in his movie "borat," stood in the middle of a muzzlim camel beauty contest and started singing the HaTikvah (Israel's anthem)
wonder what would have happened then?
