The genuine Indians know they have a lot to lose (their preferred status as “wards of the state”) if everyone claims their heritage - and having less than 1/1000 qualifies one as a “native”. Smart of them to come out against her.
You said it. BTW I laugh every time when someone claims that they have Indian Heritage.
BTW my father's ancestor came during the Thirty year war 1618-1638 to Germany from Sweden (Malmoe). I have never claimed that I was Swedish.
Good point.
