If anyone tried to terrorize us, patriotic but deranged individuals would act against their communities... if the Muslims continued to attack us, and refused to condemn the attacks, they would be attacked in spades here. Hate crimes would go through the roof. Mosques would be shot and burned. Even if the Muslims attacked nobody but Jews, the vast majority of "counter-hate crimes" would be carried out by non-Jews. Good ol' boys protect the liberal yuppies by threatening to git medieval on random Muslims.
Xem, that's the difference between emasculated cultures, like the Europeans', and ours: American men, best in the world.
It's not entirely a good thing. The only person to have been killed so far was a Sikh (and they aren't Muslims).
