I like what the Aussies say about the analogous situation: "Aboriginal."
So do I but Lib would probably call it "abortion". It just rolls off the tongue better. LOL
If you're using the English language to describe yourself, native American works fine for the edjamacated PC sorts, but for the masses, it sounds like any regular old American--which isn't the meaning meant at all. Aboriginal has the same flaw, since nobody will really have a clue what it means because the PC classes. And it will cause confusion between Australian and American aborigines, not to mention that I understand there is lately even some PC objection to the term aborigine down under.
I don't care if fishy is a left handed lesbian Viking. And I don't care if you call me cracker or redneck--silly names don't hurt when you can call silly names right back. But you'd damn well better have the ability to address my opinion if you want any respect from me, and the grand old osprey can't even pull that off, preferring instead to take the cheap shot of claiming prejudice just like all the other race-baiters, when he can't argue anything I've said, distracting from the issue I've raised instead of trying to demonstrate how what I've said isn't logically so. More PC isn't the solution.
