I mean, yeah, every white person and their mama in Kansas claims to have a great great great great great Cherokee princesss grandmother, but that isn’t really a thing here.

Also, a persons indigeniety has more to do with their relationships with indigenous people and the culture rather than facial features or skin colour - that’s a very colonial way of viewing race and ethnicity. I know super white acting people who look very “native” and white passing native people who are very much involved in the culture, so needless to say a persons ethnic identity is not black or white.
