And, addressing Freepers in general, yes, I know A-rabs are also semites. But in common usage we know to whom the term ant-semitic applies.
I had a Jewish friend in grad school in Austin. She was from Connecticut and her family was almost literally afraid that when she moved to Texas that she would be sent to a concentration camp. She was sort of surprised that she found less anti-Antisemitism in the South than in the N.E.
It is absolutely true today that there is far more anti-semitism on the American left than on the American right. My parents told me that American Jews of their generation considered Republicans antisemitic because the Democrats in the 1930s tried to lift immigration quotas to allow Jews from Europe to enter America and the Republicans blocked them. (I don't know if that was in fact true; if it was, it may have had more to do with immigration policy in general than with anti-semitism. I haven't studied that aspect of history enough to comment.)

The "we're not anti-semitic because we don't hate Arabs" thing is a modern leftist dodge. The phrase "anti-semitism" was in fact coined by a Nazi in the 1930s to come up with a "scientific" name for what had until then simply been called "Jew hatred."
