America is genocidal, sure, but so is every single other society in the history of civilization. America is exceptional because of the technology and the art it contributed to genocide, which is the goal of every civiliztion, remember. Pointing out the difference in scale of US atrocities just prevents us working together for greater justice.

I can't site any sources cuz this was a while ago, but I looked into it and apparently there is some debate over this among historians. It's likely some slave labor was used building the pyramids but generally the guys doing most of the actual masonry work were paid freemen, cuz most slaves didn't have the craft skills to do that kind of work.
