I have yet to see proof of that claim for about 10 years now, but I agree that he tends to avoid anything critical of Israel. He has clarified his stance over the years though, saying that he knows that a certain portion of Jews are into some bad stuff, just like small portions of most groups are. He does make it clear that he won't generalize when it comes to Jews, yet he does generalize about other groups quite a bit...so who knows?
