100% agree. I am a native American. Cope.

I'm an indigenous Texan. I'll be using that.
The issue is ambiguity. "Native American" is the name of a genetic race like Caucasian and Mongoloid, and it is used to denote a land of birth. I am both (well, not much the prior, but I can trace lineage).
Ambiguity is the enemy of clarity and the friend of deceit.
