Where I was, it was absolutely, "I'M an Indian and proud of it, and you're not going to tell me what I can or can't call myself, so I can use it. YOU can't." So the non-aboriginal staff of every race used different words, because you can't automatically tell that "Indian" is meant respectfully, while it's easier with "First Nations". I mean, I still can't hear my white grandmother say "Indian" without hearing either "East-", "drunk", or "dirty" inaudibly attached to the front of it.
