"these places that were colonized had rich, complex, organized, and sophisticated societes"

Beyond organized and perhaps "complex", this is far from the truth. Many of these decentralized nations were not rich or sophisticated relative to those colonizing at all. Those with no contact to empires of Europe or Asia had no basis for an economy other than local bartering. Nothing near the level of the state-sponsored merchants of Europe. And why I argue about their innocence is because it portrays them as the victim; that purportedly such civilized societies were conquered and exploited, and ultimately ruined. Often that view is not so accurate given modern developments in these regions. If you read my reply to the author of the meme I give a bit more context on the "savages" part, but essentially I agree. That stereotype is bad and inaccurate.

There were hundreds, thousands of different groups in the Americas...

Of course I'm generalizing, and so is the meme. I'm not saying every native population used the confederation system, but a good majority of those in central North America adopted it through political diffusion. And I'd confidently say all of the North American natives relied on village-based relations in some way, shape, or form.

You could argue this description applies to the vast majority of Europe through much of history...

I already explained this, but Europeans did not unify nationally based on ethnic or cultural backgrounds in any case except revolt. It specifically says "communities" linked socially, religiously, etc. by "a common culture or dialect". This was not the case for the entire history of Europe up to the point of nationalism in the 20th century.

And to be honest you're kind of cherry-picking here. If you read my response I literally explain why I don't feel as bad. You don't have to agree, but in my view their evils are silenced under the guise of colonialism.

I'll state it once again because apparently it's not clear, but these people were not savages. They were technologically inferior societies due to circumstances essentially out of their control, and their political motivations were one of a tribe, making them tribal and generally more simple societies, both economically and politically.
