From what I’ve read of preferences among Native Americans regarding terms of identity, is that most would not take “native”as a slur, but they may consider some personal refinement in terms more acceptable.By whom? https://en.wikipedia.org/wiki/Native_American_name_controversy
I guarantee you that the term "native", as in your term "native ancestor", if applied to them personally, will be taken as a slur by many Tribal members in my region of the US.
I would say that Lizzie is quite comfortable with the term.It's not Warren's nomenclature, at any rate. She, at least, knows better than that.
Full statement by Elizabeth Warren on ancestry
The following is the full statement provided to the Boston Globe by Elizabeth Warren’s campaign Wednesday night regarding her assertions of Native American ancestry.
Growing up, my mother and my grandparents and my aunts and uncles often talked about our family’s Native American heritage. As a kid, I never thought to ask them for documentation - what kid would? - but that doesn’t change the fact that it is a part of who I am and part of my family heritage.
The people involved in recruiting and hiring me for my teaching jobs, including Charles Fried - solicitor-general under Ronald Reagan who has publicly said he voted for Scott Brown in 2010 - have said unequivocally they were not aware of my heritage and that it played no role in my hiring. Public documents that reporters have examined also show I did not benefit from my heritage when applying to college or law school. As I have confirmed before, I let people know about my Native American heritage in a national directory of law school personnel. At some point after I was hired by them, I also provided that information to the University of Pennsylvania and Harvard. My Native American heritage is part of who I am, I’m proud of it and I have been open about it.
The people of Massachusetts are concerned about their jobs, the future for their kids, and the security of retirement. It’s past time we moved on to the important issues facing middle class families in Massachusetts.
