While I probably wouldn’t make “Indian” my first choice due to the negative historical connotations, we do have plenty of formal institutions – indigenous-led institutions among them – that use Indian in the name. So it’s bound to come up in casual discussion.

I think what is most important is that, if a group or individual expresses a preference, we should honor that preference where possible.

Even the term “indigenous” is problematic. It was the term used by the Romans to describe the subjugated peoples in remote provinces.
