Kanehsatake 270 Years of Resistance helped change that when I watched it in my early 20's. I just watched it again recently and it is still raises the hair on the back of my neck. Here is a little description of the film:
On a July day in 1990, a confrontation propelled Native issues in Kanehsatake and the village of Oka, Quebec, into the international spotlight. Director Alanis Obomsawin spent 78 nerve-wracking days and nights filming the armed stand-off between the Mohawks, the Quebec police and the Canadian army. This powerful documentary takes you right into the action of an age-old Aboriginal struggle. The result is a portrait of the people behind the barricades.
