This is one account and, even then, it's highly debated. Other accounts have the meaning referring to simply the color of the skin of native tribes. That there isn't an official agreement on just what it means makes those in the C.O.C. offended by it look that much worse.
As for the people that were surveyed not being Native Americans? Take that up with the Post. But, if you want to discuss raw percentages, 90% of tribe members surveyed said the name was not offensive while 10% said it was. Once again, that is a LANDSLIDE. And those were just the percentages of those who belong to a tribe.
I'm really sorry that you're probably one of the white people I talked about in my OP, but you have no footing here when so many of the people who are supposed to be offended by the word, at least according ton the C.O.C., are not.
