I suspect there is another group that will need to weigh in for an interesting answer regarding race in this film: mixedblood members of any culture have a foot in at least two camps, though complete exposure to both doesn't always happen. Since the comparison has been made so often to American Indian culture, looking at the scholarship of such individuals as Gerald Vizenor, Louise Erdrich, Michael Dorris, Louis Owens, Linda Hogan, Leslie Marmon Silko, Wendy Rose and the scholars who know them so well might shed some light. I expect those responses either aren't out there yet, or haven't been repeated (or retweeted) as widely.
