While they had some admirable qualities, the plains Indians (why don’t you call them native americans?) were a stone age people and modernity was advancing. They were in no position to stop it, it would inevitably consume them. It has always been that way.
I grew up calling them Plains Indians and I will die calling them Plains Indians. The fact that their people have been in the America’s for 30,000 plus years is understood and I don’t feel the need to kowtow to any PC bullshit from lefty Karens- you included.
Modernity will always advance until we are destroyed by the modern notions of communism and transgenderism.
