Anyway, while I'll accept that this idiot is a Jew, just because you have a "Jewish" or "Jewish sounding" name doesn't mean you're a Jew.
Many think Norman Jewison is a Jew he isn't.
Anti-Semite writer Alfred Rosenberg was a major source for the Nazi.
I went to an interesting talk by a Catholic monk and a rabbi. The names were Goldberg & Fratello. Brother Goldberg & Rabbi Fratello.
In any case, technically you're Jewish if your MOTHER is Jewish. So the last name means little. So, Jennifer Connelly & Maggie Gyllenhall are technically Jewish. Gwenyth Paltrow & Ben Stiller, not so.
