Sorry, that isn't going to fly in a court. We don't work on what religion a person is, but whether or not you have the rights of a citizen. An atheist is a Jew is a Hindu is a Buddhist is a Christian is an animist is a Muslim under our Constitution, and I wouldn't have it any other way. Whatever approach is used to get rid of dangerous people, I emphatically oppose a "religious test" before someone can be a citizen.
But we can certainly discriminate in favor of nonmuslims, and against muslims, in our immigration policy. No reason to import members of a group that always create trouble whenever they acheive a certain percent of the population.
Islam isn't a religion. It is a competing political system that is incompatible with the Constitution and the ideals of the founding fathers.
Moslems claim to be citizens of islam first. They've already renounced their citizenship and can be treated as non-uniformed enemy combatants
"We don't work on what religion a person is,"
Islam is not a religion. It is a terrorist organization whose plan of action is to eliminate every other religion on the face of the earth and impose religious rule everywhere using murder and the threat of murder. Organizations that have plans to murder and intimidate to force their religion on others and and who have overthrow our government are illegal. Flies in court!
