Until you ask them. I live in the Northwest, where there are a LOT of Indians around and most of them I've met self-refer as Indians. The only folks around here who insist on "Native American" are the PC-folk, both white and native, and most everybody else just giggles at them, both white and native. "American" is questionable as well, since America was named after an Italian, Amerigo Vespucci. "Turtle Islanders" won't work 'cause they don't all subscibe to the same tribal mythos. What to do? How about we worry more about their civil rights and less about what "we" should call "them"? I've been on both sides of the PC terminology argument (as a white man having spent a considerable amount of time married to a black woman) and have just come to the conclusion that there will always be something to be offended at if you want to put all your energy into being overly sensitive in meaningless ways. VERY few words carry the extremely negative conotation of the "n" word by the way. "Redskin" comes to mind, but even that has been manufactured into a non-PC term. It survived in a benign sense long after the negative attitudes about Indians died down, and was not entirely pejorative like n*. Sheesh. Sorry, I kind of went into a zone there. But I'm better now.
