:::::::Wait a second. You're saying "Native American" is basically a nationality? Can you provide a reference for that, because it seems like an unusual interpretation? So again, you'd say a kid born to two legitimate Native American parents on Mars, who never became part of the "community" wouldn't have any right to call himself native american?  
 :::::::Additionally, in the policy discussions regarding race, ethnicity, religion and gender, nationality was also discussed as a potential ambiguous category. For instance, if I take a Mexican kid at 6 months old to the states and raise him here so that he speaks English and is essentially 100% culturally American, do I continue to call him Mexican simply b/c he doesn't hold US citizenship? The point is that there's a "technical/legal" definition to what "American" means, but there's also a cultural definition.
