Seems like a resounding vote of non-confidence in their own God that they should threaten murder to protect Him. On the other hand, if you beat your dog long enough he's going to bite you.
What I'm curious about is to what degree are we creating Islamic extremism? Americans are apparently disturbed by huge numbers of Mexican immigrants, but are generally not sympathetic to the plight of the Palestinians. In 1900 the Jewish population of Palestine was about 2%.
What if China and Russia supported Mexican terrorists in declaring an independent state in Southern California? Would violent opposition be justified? Why not when Britain, America, et al, support Jewish terrorists declaring an independent state in Palestine?
Another interesting obervation I heard a while ago: Osama Bin Laden's money comes form the sale of Saudi oil to the west. In this respect we fund both sides in the "War On Terror" where it's mostly Islamic people who die.
It doesn't burden my imagination to sympathize with Arab frustration. I think that to see the problem as theirs, in our democracies, is to be the problem.
