Re: "only block those [..] who have never entered the country previously"
"those terrorists who scout the target area months or years in advance"
I call those people White, Racist, Christian, Fuckheads. You dirtbag Christians were bombing the US well before the Muslims got the idea. And you're all immigrants! Every last White American Idiot is an immigrant from some other country, not North America. Still, don't let your hypocrisy hit you in the ass on the way out!
