The man's talking about class differences in general though. Pretty sure those predate us apes even knowing there were other different colored troops.

Either way it kind of feels like a bit of a chicken and egg discussion. Were we hierarchical animals first, then leveraged arbitrary and irrelevant traits to enforce that hierarchy, or vice versa.

To me it's really simple. You adress class issues -> you adress "culture war" issues (those disproportionally impacted get disproportionately addressed, as they should be). You address "culture war" issues -> shitshow ensues.

I know what I'm gonna focus on.
