Good points. I knew about all that but never hurts to get a brief refresher.
Also, the revisionist idea of “peaceful at harmony with nature” native Americans is garbage. Various tribes had wars with each other involving extermination of entire tribes for centuries before Europeans even knew North and South America existed.
We have to remember the meme though pushed by our “education” system: white man bad, everyone else except maybe Jewish people good.
As many on this thread have pointed out, the indigenous people when Columbus arrived in 1492 had their own issues with other indigenous peoples, specifically the Caribes (from which the word “cannibal” is derived)
The Caribs were brutal and vicious, apart from simply eating those they conquered.
They were rightfully feared by other tribes who I will simply refer to as “Others”, because that is how it generally broke down. The “Others” whoever they were, were pretty happy to see Columbus and wished to have good relations with him (probably until they figured out they fully intended to stay at some point) because they were a powerful counterpoint to the feared Caribs.
The myth of an idyllic, peaceful environment of indigenous people is just that. But like both the Caribs and the “Others”, when they encountered Europeans, cannibalism may not have been the primary issue, but warfare, slavery, and being conquered by others were still issues, ones they could not overcome due to the disparity in cultures.
