Rob Eshman, editor and publisher of the L.A. Jewish Journal, says relax:
I found these reactions more annoying than MacFarlane’s comments, which varied from the very funny to the remotely funny, but never came close to anti-semitism.
Seth MacFarlane was joking. He was poking fun. He was mocking the widespread understanding that Jews are disproportionately represented in the entertainment business. This fact comes as a shock to exactly no one, and the idea that joking about it “feeds” anti-semitism misunderstands both the nature of humor and of anti-semitism.
One thing humor does well, even better than press releases, is diffuse prejudice. It does that through mockery, exaggeration and sometimes by just bringing prejudice to light.
