Immigrants are ‘guests’, not citizens, so we can make them wear pink tutu’s if we want or just bar them or kick them out at will. They are NOT citizens! So I have no problem with this. We can test them however we want, its the smart thing.
Just because you can doesn’t mean you should. If you would silence Christians who would otherwise be your best friends because they want wise policy, you can, but that doesn’t mean it is not foolish.
