It looks like I was right about The Passion reinforcing existing anti-Semitism. From Al Bawaba:
Gibson's film has stirred a religious controversy in Kuwait between majority Sunni Muslims who oppose the movie and the emirate's Shi'ite Muslims who call for showing it. The authorities, meanwhile, have not decided either way. Tabtabai went so far as to outlaw the film's screening by any Muslim country and But the emirate's leading Shi'ite cleric Ayatollah Mohammad Baqer al-Muhri said there was nothing wrong in showing the film and called on the authorities to approve it.
According to the news agency AFP, it was argued that the film is a good opportunity to reveal the crimes committed by Jews against the Christ and many other (religious) prophets. "We sincerely respect the Jewish religion and Jews, but not the Jewish Zionists, and we believe in Jesus and Moses like we believe in our own prophet," he added.
