Yes. I don't remember the name of the civilization, but there was an entirely "peaceful" society that existed for several hundred years, until Christopher Columbus showed up, and raped and murdered them all.
No group of people has ever been peaceful with each other, let’s stop this anti-west fantasy and start talking about real problems, like how to fix democracies and capitalism
You didn't bother reading the source. No they didn't. Stop trying to whitewash history. They had ceremonial battles that included wooden "weapons" to resolve disputes. They didn't kill each other.
Sure between other nations of Native Americans, on the main continent. This One group lived on one of the larger Carribean islands, managed to not have any war, because no one else came out that far.
I'm NOT talking about any of the other nations that existed on the continents. You asked for an example and I've given you the only historical example I can think of. I don't even include the Sentinel Islanders here, because while they haven't been recorded to have participated in a war, they are clearly hostile to outsiders. The Taino didn't respond with any hostility, to the point that Columbus made a remark in his diary that they would be easy to make slaves of the people, since they had no will to fight back. They were a communal society that didn't have neighbors to fight with. They also lacked the gold and silver that CC was looking to pillage.
So humans are so shitty even if one group is able to miraculously come up with a non-violent society (perhaps partially due to geographic isolation, they will be found by the violent humans?
we all exist on a constant razor's edge of anarchism and fascism. which grouping our group falls into comes down to how we as individuals interface with our collectives. the conclusion isn't "humans are so violent that even the peaceful ones will someday be wiped out" it's to ask "what did they figure out to resist the pull to fascism that the rest of us haven't."
