"More than its blunt critique of Israel, Israeli policy, and Israelis, the cartoon points an accusing finger at all aspects of the Jewish establishment of the United States. Eli Valley is clearly no outsider to the Jewish community. The cartoon jabs at Jewish schools, camps, Israel advocacy programs, and even pokes fun at a sociologist whose work is well-known in the Jewish world. Valley himself is a regular cartoon contributor to The Forward newspaper.
We may disagree with the cartoon's sentiment, but we cannot accuse it of ignorance."
Here's the link to the comic, Dawn of the Chimpanzee!, in its original home on Gawker, where the comments forum is surprisingly thoughtful.
Thanks to Alex Sinclair for the tip-off on this. Voonga...Voonga!!
