Almost. They keep marrying out of their race (many think they are native to this continent because they are enrolled in a tribe by birth, even though they may have as little as 12.5% Native blood).
In the U.S. there's only some hundreds of thousands of real (I mean real) natives, but millions of mixed people with tribal citizenship that think they are native to this continent because of that.
Kanien:kaha'ka: Races exist, whether you like it or not, and if you are of mixed blood (nice how you try to discard that by associating it with dogs) you are not native to this continent, as your roots are also found elsewhere.
Ii’ni’ da’ałhosh: Then the other 13% are not native, actually, because they possess mixed heritage. They are merely tribal citizens (practicing native culture does not make you in any way native to the American continent).
Wiininiskwe *Ajidamoon*: "Fullblood is a nonsense word that belongs only in dog shows." Why do you say that? Is it because you are of mixed heritage (with a non-native, which makes you not native to the Americas)?
Salish: That's media rubbish. Races very much so exist. Only ignorant, blind people who follow everything their government and media tells them would think a Nordic man doesn't exist, nor does a Sub-Saharan African man, that they're both exactly, identically the same.
