My wife is an Indian (Sioux and Oneida) and has no problem with Indian team names/mascots except for two: the Redskins because light as she is she was still called a redskin, and Chief Wahoo, because it’s so damn insulting.
Then again, like all tribal Indians, she considers that their business and not ours. There is no faster way of getting on a tribal Indian’s nerves than telling them what they are supposed to think and why. Or even worse, think we are one of them. We aren’t. We come from over there. No matter your color or creed or ethnicity, if most of your ancestry did not come across the Bering Strait land bridge, you are not one of them. And you will never be, no matter how many pow wows you’ve been to. Not that they would ever tell you that. They’ll just roll their eyes when you turn around.
