@lifewithtrees @pathfinder @Tamtam @autistics Indeed, it is countercultural in almost every culture. Cultures generally favor conformance. I'd argue that it is almost one of the definitions of a culture: it's what defines someone who is part of the tribe from someone who is not.
Tribalism and, so, fear of the foreign is an aspect common to many species. I have to imagine that this naturally evolved from the scarcity mindset needed to survive. Capitalism thoroughly encourages this mindset. For that matter, it keeps us concentrated more on our same and near-rung social competitors and far less so on those further up the contemporary feudal hierarchy that we live in. And that's how capitalism likes it.
