Montana Jim, I don't know your nationality but I'm sure there are other names for it you might have a problem with. Sometimes people try to change history by re-inventing meanings of words. Like "Red neck". It was a derogatory term until a country song was recorded saying "Red neck" was just a working man. NO, wrong.
I believe "First Nation" fits way better than "Indian, Injun, Redman, and the rest. It also speaks poorly to the terms given for things that are not true. Indian giver, Indian tobacco, and Indian summer.
