If “Dances with Wolves” had held true to the book, it would have been filmed set amongst the 1860’s Comanche culture, not the Lakota one. Many of the whites that I know don’t have racial guilt about what was done to the red race, and THAT is unfortunate. Having seen a recent interview with Cameron by Charlie Rose, you know he didn’t mention First Nations folks once. He did give a timeline which indicated he wrote the original short story for “Avatar” when he was not much more than a boy. Perhaps io9 just was feeling the need to slip in a (lengthy) word edgewise. Most white guilt, as you call it, is misplaced, and leads to a patronizing attitude. Awareness and appreciation for other cultures on the part of “non-indigenous” citizens (our ancestors were ALL indigenous to somewhere) is where I’d like to see things go, but attitudes/approaches of people like io9 don’t seem to be offering any improvement in the situation.
