Well as Devil’s advocate, look at how people in Japan reacted after Fukushima. The world was awed by how awesome their “community spirit” was - nobody denied they exhibited far more social cohesion, sacrifice and civic responsibility than would ever be on display in the US.
That’s a cultural difference on display. Culture is not determined by race, so let’s not conflate the two. Culture is something you are immersed in and it does influence behavior.
There are also massive downsides to extreme cultural cohesion, looking at it another way.
But let’s not deny that social culture has a bearing on individual and group behavior. It has a massive impact. Conflating that observation with race or _racism_ seems a particularly unhelpful neuroticism of the US.
