My step-grandchildren are about 1/32 Delaware, from Oklahoma. Can they say they have Native heritage?  Of course. Is it true? Yes. Is it relevant?  No.

Warren didn't get her teaching job because she was 1/32 Native American from OK, or whatever. She got it because she was great at what she does. She also came from a poor family, went to a community college but reached the heights of academia.  In case you hadn't noticed, her IQ is probably 50 points higher than yours. I don't care if you went to Trump U. That is not a credential.
