Cartoons, insults and hypocrisy

Been reading about the huge protests against the cartoons, had a few thoughts:

The majority of the protests are in places where there is very little freedom of expression. I mean, Syria would not allow huge street protests against corruption in its own govt, which probably happens to be more relevant to the peoples' day to day life than those cartoons.

Arab media has people calling for destruction of the Jews and Israel, why are such calls for genocide not "objectionable"? No protests? So saying you will kill a few million men,women and children is OK, but insulting a prophet is really bad?
