He thinks that as a matter of fact, banning certain immigrants would help prevent an illiberal culture from forming. He might respond that, given the facts, we don’t need to censor people, indoctrinate them, or ban certain religions. He might be right. But we can still ask him, “Would you in principle be willing to do those things, if the facts were different? If, e.g., allowing people to convert to Islam turned out to be just as dangerous as you think allowing immigrants from Afghanistan, would you favor banning Islam, in order to maintain a liberal culture committed to the rule of law?” We doubt he’d say yes.Yes, we can have free speech, freedom of religion, and democracy as long as we do not let in too many people who are opposed to those principles.
Islam is not just a religion. It is a belief system that is opposed to those libertarian principles.
If half the population wants basic freedoms, and the other half are opposed, then that is a recipe for war. Yes, it is sometimes to fight for freedom. I have no problem saying that. The strange ones are the Libertarians and cuckservatives who promote policies that will ultimately destroy what they stand for.
