Claiming that all people are like this everywhere is tantamount to genocide apologia because it implies that there’s absolutely nothing out of the ordinary about genocide. You’re basically stating this is the natural order of things and people are gonna just do this whenever sufficient political power is amassed.

That is absolutely false and ahistorical, genocides are thankfully not as common as white westerners like to pretend they are (just because they’re always involved in them), and it’s not because there haven’t been other societies in a position to enact them.
