I think this speech that ticked off the Muslims has a very subtle anti-Semitism to it. I'm surprised i haven't heard anything about this, but it wouldn't surprise me if no one else caught it. Throughout, Benedict spoke of Hellenism as the source of "reason" within Catholic culture and mentioned Islam and Protestantism as attacks on Hellenic reason. He didn't mention Judaism, but then, he doesn't have to, if he speaks of Hellenism as the primary source of reason in a religion that started out as a Jewish movement.
