>AntiSemitism is hostility toward or prejudice against Jews as a religious, racial, or ethnic group. It is specifically used in reference against jews, but technically, lately has been used in reference to denote against Arabs as well. I think in this case he meant against jews considering the comments Ahamdinejad has made against Israel.

Exactly the contradiction in the common usage of the word that I wanted to point at. Look at http://en.wikipedia.org/wiki/Semite - Arabic is a Semitic language, and there seem to be sufficient genetic links to prove that Arabs, Jews and Syrians share a lot of ancestry.
