Enjoyable post generating a lot of non abrasive discussion.
However, I disagree with the acceptance of the term Native American. Indian, agreed, not a particularly good description, but it does have historical validity, in that it was the main term used for the description of the indigenous as a group, for so long in this country.
For one, I do not have any Cherokee or any other of the various indigenous tribes' blood, that I am aware of, in my veins. And yet I consider myself native American.
But being a native then adding an European context to it, the America part variously thought of coming from the name of the Amerigo Vespucci or perhaps from the term given it by the old Norsemen, that apparently fairly commonly plied the North Atlantic prior to Columbus' "discovery" of America,
Amteric, meaning district or land of (Leif) Eric...or
Ommerike (oh-MEH-ric-eh), an Old Norse word meaning "farthest outland."
Seems our native population should have a name of a more indigenous origin, IMHO. And of course, the indigenous may not have been the first here, either. You have the whole Kennewick Man thing to deal with.

And again, I take a little bit of umbrage as I, too, consider myself native American.
