In the West, fortunately, it scarcely exists now, though it did in the past.
Obviously wrong. Is he just ill-informed?
There is, of course, what the Anti-Defamation League calls "the real anti-Semitism", more dangerous than the old-fashioned kind: criticism of policies of the state of Israel and US support for them, opposition to a vast US military budget, etc.
Clever move. Name an enemy. Attribute an untruth to it. (That this group said the "real" anti-semitism is "more dangerous" than the "old"...an easy, false strawman to tear down, plus he relocates the argument to the US military bugaboo.
In contrast, anti-Arab racism is rampant.
"Arab" should read as "Islam". The study of it is a threat to Chomsky's limited world-view in sync with Arab obsessions with Israel and Jews.
The manifestations are shocking, in elite intellectual circles as well, but arouse little concern because they are considered legitimate: the most extreme form of racism.
I haven't seen this, but perhaps for Chomsky any reading or analysis of Arab opinions, etc. that don't confirm his projects.
Of course, he could just be pandering to his reader-base, the ones who give him money via book-buys.
