Not essentially "cringe-worthy history" but a recent (and fairly hot) thread on AH.com poses the interesting counter-factual question: "
How would non-Western colonizers have treated Indigenous groups?"
(Personally, I fall into the "humans are broadly similiar" thesis, and that colonization is fundamentally disastrous and deracinating done wherever and by whomever, but it is
telling that while certain comments put forward the idea that the West was the best native Americas could have got, the opposite - that perhaps certain non-Western groups could have done better, or at least less worse, in the Soviets vs Nazis style - seems almost automatically shut down.)
