Tl;Dr: it's tricky. and because it's not that simple.

I don't know your background and maybe you're from a first nation or tribe, but there isn't a common agreement between the populations of existing tribes and nations on what is offensive or incorrect. This isn't to say that any term is acceptable, but Indians, however incorrectly labeled by a colonizing group a few hundred years ago, is literally how some choose to identify themselves here in North America.

I say this as someone from India and event there, there isn't a common agreement or knowledge to arrive at an "inoffensive" term for folks who live here. Most just use the descriptor left by the British and say "Red Indians" with no malice implied.
