> You'd think it'd be easy to use ritual vivisection, human sacrifice at scale, organized child murder, and cannibalism [1] as an absolutely unambiguous black-and-white line by which to demarcate civilization from barbarian savagery.

We might as well add to that list treating humans like property, the mass murder, mass rape, and mass killing of civilians by invading armies, child labor, genocide, things like pogroms and lynchings, separating children from parents at scale, etc ...

So, who is exactly left on the “civilized” side of the line now?
