“That seems to be your hobby-horse:” ... more like a pseudo-intellectual strawman, wearing red herring dressing.
I'd say so, too, dear brother in Christ!
But then again, these "isolated tribals" have been deliberately kept in the dark about their own history and culture for decades now. Thanks to Dewey's idea of public education, which has nothing to do with basic knowledge, the transmission of one's inherited culture, and the honing of critical thinking skills, but only with "adjusting" people to the brave new world that he and his fellow progressives were cooking up for us, around the turn of the 20th century....
Never let history, actual human experience, accumulated human knowledge, let alone the U.S. Constitution, stand in the way of their coming expert, scientific Utopia!
Therefore, education = propaganda. Designed to fit us into the new realities that are about to be imposed on us "from above" — from the self-selected intelligentsia that commands power to compel us into adjustment into their feckless "norms" of a second reality that has no basis in Nature, human or more generally.
Oh, the poor dears!

When there’s an incapacity to answer, parting insults are free to dispense.
