Proof that I am a Native American

A while back, a front page story in the  local rag of record, The Arizona Republic, implied  that one is either a native American, a Black, or an Anglo. Now with my kind of surname, I am certainly no Anglo. And even though I am a 'person of color,' my color inclining toward a sort of tanned ruddiness, I am undoubtedly not Black either.

It follows that I am a native American. This conclusion is independently supported by the following argument:

1. I am a native Californian
2. California is in America
3. If x is native to locality L, and L is within the boundaries of M, then x is a native M-er.
Therefore
I am a native American.

Note that (2) is true whether 'America' is taken to refer to the USA or to the continent of North America.
