My paternal grandma and grandfather are both from Guatemala Mexico, but my dad is was born in mexico , what does it make me?
It makes you "of mexican descent" If you are enrolled in a tribe, and have a CDIB- card, you are also Native American (mind the caps there)
It makes you a human being who has succumbed to the weird racial stereotyping that seems to have permeated American society.
Where were you born? That's what you are.
