I don't know anyone who still says 'native american' (in real life, that is). Usually American Indian, Indian, or a tribe name. That's sort of 80s-90s, 'native american.' 'Indian' isn't insulting in any way. And it's just as stupid a term as 'native american.' So I say go with the name we've been using all this time. At least it's got some history, and doesn't reek of excessive political correctness.

How is 'NA' more respectful, anyways? It's still taking the name of a non-American Indian (Amerigo Vespucci)...
