Many many arabs want to kill Americans. 19 of them succeeded in killing lots of Americans just two years ago. You must have seen it. It was in all the papers. Other arabs danced in the streets when they heard the news. In dealing with the arabs, which we have to do collectively, it would be idiotic not to bear in mind that large numbers of them are hostile to us. In that, we and Israel have a common enemy.
By the way, minorities commit crimes in this country at a highly disproportionate rate. They have self-appointed "advocates" from among them who make the problem worse. And yes, "many" of them want to kill white people (of whom they've killed more than Arab terrorists have killed Americans). Does this justify racism in your view?
