Perhaps a more interesting question: do people here consider Karl Marx's "On the Jewish
Question" an Anti-Semitic work? I've seen people argue both ways.
I don't know if you're listening to the
Revolutions Podcast (everybody should be), but they recently had a long bit on this subject. They are in the prelude to the Russian Revolution and are currently running through the Marx vs Bakunin* stuff, they like everybody else that wasn't Jewish (and many that were) were certainly anti-Semites, if only in words (which should be enough).
*and I had never heard of this guy before
