You have a funny way of expressing that.
And I quote:
But he does NOT belong in the USA after what he said.
First: Who are you to say who "belongs" here and who doesn't? America has never had a king. He belongs here if he chooses to stay here. Where he does NOT belong is as a guest in your house, which is your right and a good thing all around.
Second: You have no way of knowing whether he would be happier somewhere where his views were official policy. You, however, make it plain that you would be happier if he were in a place like that, which would also make this place more like somewhere where your views are official policy. See reference to kingship, above.
