Muman, I don't believe in church infallibility, but some Jews do the same thing. There are many Jews who consider the opinions of certain rabbis, such as Rabbi Ovadia Yosef, to be divine and the direct revelation of G-d. Because Rabbi Yosef ruled that land-for-peace is halachically permissible in order to "save lives", directly supported Oslo, and stated that the Arabs are the brothers of Jews, hundreds of thousands of Jews supported these policies, which led to utter and complete disaster for the Jewish state. Granted, the magnitude of this may not have been as great as that of anti-Semitic popes who ordered crusades, expulsions, and pogroms, but it was still terrible.
