Adam Levick has a paper on the existence of anti-Zionist cartoons that employ antisemitic imagery on “progressive” blogs such as Daily Kos, Mondoweiss, MyDD, and Indymedia. It’s worthwhile to take note of this phenomenon, but I’m not sure what conclusions we should draw from it. Adam concludes that “the failure to act in the face of such clear expressions of Jew-hatred constitutes a shameful — and potentially calamitous — moral abdication” by mainstream progressives. But what if these progressives don’t understand that such images are expressions of antisemitism in the first place? If so, their failure may be less a moral one, and more one which stems from a lack of knowledge or a series of misperceptions. I’ll have more to say on this later, but for now I recommend a very thoughtful working paper on left-wing antisemitism, entitled “Anti-Zionism and Antisemitism: Cosmopolitan Reflections” by David Hirsh, a sociologist who teaches at the University of London. I have met Hirsh a few times and most recently heard him speak on this topic at the YIISA conference at Yale. His insights are important.
