The defensive claim made by some that Arabs cannot be "anti-Semitic" because they are "Semites" is equally erroneous and facile.

"Anti-Semitism is alive and well today worldwide and its major victims are Arabs and Muslims and no longer Jews. The fight should indeed be against all anti-Semitism no matter who the object of its oppression is, Arab or Jew."

Both quotes taken from a thought-provoking essay by Joseph Massad who teches at Coluimbia University, New York, in which he explores this whole tangle.
