Yeah, that's from last July, and no, I seriously doubt that the state of Oklahoma is going to go from the native Americans born in the US to the children of the aboriginals who are still around today.
I'm a proud Native American, living in California, but born in New York. My ancestry goes all the way back to Africa, so I'm also an African American. somewhat more recently, my more immediate ancestors came from Ireland on the one side and Germany on the other, but I'm as Native an AMERICAN as anyone is ever going to see.
