You hit the nail on the head: everyone is too busy grouping these separate nations together. Like there will be a reader here trying to form an opinion and say "wow that opinion from an American Indian/Indigenous/Native American person will now form my opinion since it weighs so much more" as opposed to "one part Ojibwe person has one paradox regarding the Ojibwe nation's relationship with the Lakota nation, and I wonder what the actual consensus on that specific issue is with the representatives of those nations and the US Federal Government". There are hundreds of separate nations within the US that are barely on any map. And these all need to be reconciled individually.
