Send em to the south. I'll hook em up with a home cooked meal and a shot of bourbon and they'll be ready to pledge allegiance by dessert. I had some German exchange student types I was friends with in college. After helping them find a car, getting them some furniture, cooking them a meal, and taking them to the range, they were really starting to see what all the fuss is about. One did his mandatory army time and was in awe that everyone could shoot and that we had guns in our homes. American hospitality at first, American hostility for the holdouts. I mean if your gonna be hardheaded after some hot biscuits it's on you.
