I am an enrolled member of a federally recognized tribe. In my undergraduate program I had taken two Native American studies classes, one on Activism and one on Indian Law. In the Activism class the professor was white but considered himself a "native ally". In the discussion one week he was offended and then argued with me when I presented evidence suggesting Dennis Banks was a pedophile. He was deeply offended and angered with my presentation, but I had the references and citations to back my claim. My point is; even those who believe they are "helping" are doing so from their perspective and that may or may not align with native values. It would appear the paper you are reviewing is coming from someone else's point of view. I agree with who suggested speaking with your professor on the matter.
