I had no idea it was so widespread. The "value" of the Native American one, though, compared to the vast majority of the other ones, is that it is not accusing any particular group of saying sh*t to Native Americans -- so the speakers could be white, black, latino, gay, straight, etc., or even a person of Native American blood who is disconnected from their culture. FYI we are working on one, Sh*t people say to Native Hawaiians. Stay tuned!
