My professor had a funny story that went along with her explanation. While checking out of a room at a hotel, the professor was standing by the front desk when a housekeeper came down and reported to the manager that a room, which had been rented by a couple American Indian kids, had been trashed. The manager went up and checked and came back down to the front desk. He then loudly proclaimed, "That is the last time I rent to Indians!" The professor found this funny and asked the manager, "Have you ever had a bunch of white kids rent a room and trash it?" To which the manager replied, "Yes." And the professor then asked, "Then why do you still rent rooms to white people?"
Can you see the difference?
Can an American Indian who manages a hotel in America declare that he will no longer rent to white people? That hotel would probably go bankrupt very quickly if he did.
