This is the deleted comment by ‘ElKafir’ I’m referring to, and it wasn’t the first:

We must separate ourselves from this cancer of civilization called Islam.

Mass deportations. Start with the non-citizens. Then continue with the naturalized and US born or converted muslims. Declare Islam a threat to the very existance of the Republic and its Constitution (afterall, in Islam the only accepted law is the Sharia and muslims everywhere in the world are taught their first duty is to obey the Islamic law and only after that to obey the laws of the countries they live in - with the condition those laws aren’t contradicting the Islamic laws).

Amend the Constitution, strip them all of citizenship, offer them the chance to become apostates and remain here in the civilized world or deport them if they refuse.

Make conversion and preaching Islam a crime punished either by life in prison or deportation. That would be a humaine measure when compared with the punishment for renouncing Islam in most islamic countries is death by decapitation.
