Yeah, riffing on @k00b's point, I guess the devil must be in the details. I don't feel adequate to the task of opining, but there's a few contradictory ideas in the mix: we've all probably seen regions of the world where it's a complete enjambment of cultures, where people with seemingly nothing whatever in common from a {race, culture, economic} perspective sweat together on subways and in tuk-tuks, and it's generally fine.

And these other distinctions where you can't have a civil conversation with your neighbor who, from an outside vantage, would appear indistinguishable from you. So when can you co-exist peacefully and when not? How much of reality do we have to agree on, and could we curate that process?
