If government is allowed today to bar muslims because they are muslim, then tomorrow that same government will decide it can bar Bible Studies or evangelical Christians. Cruz is wrong and Trump is right — ONLY IF you decide that the First Amendment is obsolete and no longer the law of the land.
Are you confused. This isn’t about Bible studies. Geesh
The First Amendment doesn’t apply in Pakistan or Saudi Arabia to citizens of those countries, so your argument is pretty moot.
