This fellow doesn't need to solicit anti-Jewish cartoons, all he has to do is survey the major Israeli newspapers over the years....traditional religious Jews and "settlers" are usually depicted as blood-suckers, parasites, primitives, violent, etc, etc. because this appeals to the anti-religious nature of the secular oligarchy in Israel. What would be a change would be to see cartoons in the Israeli press mocking Arabs.
