well, a lot of the more conservative christian folk didn't take kindly to ET since it parallels the jesus story... lost son, teaches people to be nice, gets a band of followers, persecuted by the establishment, able to heal and do "miracles", dies, comes back to life, leaves but tells people that he'll come back....
And a lot of the more militant Jewish folk and the segment of christian who are pre-israel... were pretty pissed about Munich, and spielberg's portrayl of the terrorists.
Spielberg in general, gets a lot of flak from older, conservative folk. He's made comments that Castro was the smartest man he ever met and such... such talk doesn't go over well with some people.
