Life is too short to worry about unintentionally offending someone. "First Nations" and "Native Americans" call themselves "Indians" -- at in American Indian Movement. As a Potawatomi fella once said to me, "Call me an Indian or better still, a Potawatomi. Anybody who was born here is a native American."

"African-American" has its own problems -- what do you call a white guy who was born into a family which has a long history in, say, Kenya or South Africa, but who immigrated and is now a US citizen?

Forget it, I'll take people as I find 'em. Always have.
