The "what an ass" comment is about him calling Palestinians the most pampered people on Earth. I understand perhaps they've received more aid per-capita, but you could only construe that as "pampered" if you completely ignore that they are the most terrorized and bombed people on earth.

He is heavily pro-Israel which is a deal breaker for me at this point. I don't think anyone could be pro-Israel unless they either don't have a decent diet of information from both sides, or they have a monstrously evil psyche. He is certain of his view, which means he is either monsterous or both ill-informed and certain, and the combination of ill-informed and certain is itself a big red flag for me.
