If they come to our restaurants, we should jeer them. If they come to our bars, we should mock them. If they come to our theatres, we should expel them. If they want to do business with us, we should refuse them. Any kind of contact whatsoever must be minimized, to the point that supremacists are as small a part of society as is possible. Does that sound harsh to you? Maybe unfair? Does it make perfect sense?
