You’re romanticizing pre-colonial life. The notion that Native American tribes lived in some utopian harmony before Europeans arrived is ahistorical. Many tribes were in near or constant warfare with each other, raiding, enslaving, and conquering long before Columbus showed up. That doesn't excuse colonial atrocities, but let’s not pretend the Americas were one big peace circle until white people landed.
well, I didnt actually claim or pretend that.

things were certainly vastly better for indiginous people before white people arrived and I dont know of any atrocities murdering unarmed women and children such as Mitch described before white people arrived- but vastly better isnt Eden and I didnt say it was
nevertheless the indiginous people of almost every colonised every country fared much better before arrival of white people ( I put almost because perhaps there are exceptions) - so, yes, my statement that it worked quite well stands. Certainly far better than after the arrival
The idea that there is some uni cultural Eden that worked so well compared to multicultural societies, which is what my comment was originally in response to, is a romanticised version of a utopia that didnt exist.
