It’s like a herd-resistance thing. Too much anti- and the thing begins to fall apart badly.
This is one reason why so many want a wall. It’s to ensure that people who are let in will have to go through a door where they are vetted as to willingness to play the overall American game. Must they be Christian or Jewish? No. But they should be willing to play along with a Judeo-Christian ethic, a bible ethic. They should not be the poop in the Christmas punch.
So how does your proposal work in practice? What are examples of individuals not “playing along”, and how would you force them to change their behavior?
