I've watched both. The part that stands out to me is that the Black Israelites were giving the Native Americans a lot of abuse; cursed at them, called them slurs and denigrated them.
Nathan Phillips ran from the chance to stand up for himself or his people against the Black Israelites and instead tried to bully the high school students. Phillips wouldn't even mention the Israelites in any TV interview being a part of the problem. Totally unreal and totally biased.
