The good folks at Amptoons found an article arguing against the anti-semitic interpretation by the Venezuelan Jewish community, with support from various prominent American Jewish groups. Apparently, "Christ-killers" doesn't have the anti-Semitic trope it has here and in Europe. Rather, in liberation theology circles (who see Jesus as a socialist), "Christ-killers" refers to capitalists, not Jews, and that is who Chavez's quote refers to. This actually makes sense given the full context of Chavez's quote, so I'll give him the benefit of the doubt.
So is Chavez not an anti-Semite? I wouldn't go that far. His claim that Israel's Lebanon war was "perhaps worse" than the Holocaust strikes me as pretty virulently anti-Semitic on its own. But fair is fair, and even though I discovered Amp's post eight months after it appeared, it appears I was wrong in this case and I wanted to set the record case.
