Intelligence isn't a substitute for knowledge. I actually like that movie but also know it's ripe with propaganda. It stars a jew playing a righteous white dude. What do you expect? It's definately blame whitey propaganda. That said, at 160 IQ, your dad should know well the need for citation and authenticity of claim. Likely his education taught him better. It's also true some tribes did practice the stick shit, but that was to showboat your personal bravery. It was never a replacement for actual warfare. And they did love some warfare. Entire tribes and even higher civilization (which appear to be aryan in origin) were genocided by each other. Crabs in a bucket is their legacy. White men were assholes at raping America in general. You should see what white men in America and Europe wrote at the time. America has still yet to recover. Not even close. Few people to this day understand how amazing America was up until the 1900s. In fact, the raping of America is said to have rejuvenated Europe and especially England. America's natural wealth rejuvenated another continent. It's never been the same since.
