First Nations - what does that make the rest of us, second nations?
Natives - isn't anybody born in Canada a native Canadian? Unless it's meant in "the natives are restless" context - not complimentary to anybody
Aboriginals - at least correct. I like to shorten it to abo tho, and that seems to get everybody all excited
Indians - too confusing now that we have so many real Indians living here. But then I guess they are Indo-Canadians.
What about Red Man, since aboriginals seem to like to call us White Man?
What about Canadian to describe anybody who is a Canadian citizen, no matter how long they've been here? Since aboriginals now have all the rights of other Canadians (and then some) how about assuming the same responsibilities (ie pay taxes) and we can all just be Canadian together and buy each other Cokes.
I'm used to saying Natives. I never liked the term "First Nations" myself, and Aboriginal just...meh. Indian isn't really usable, since it was Columbus' mistake when he thought he was in the East Indies (which I think he figured he was in Indonesia, not India), plus Indians (who I commonly refer to South Asians anyway, to prevent pissed off Pakistanis) are more common in North America to really use it anymore.
