Newmark's Door

This piece by Ross Douthat in the New York Times is over a year old, but seems just as relevant now.

But no less than Brexit-voting Cornish villagers, our global citizens think and act as members of a tribe. 

They have their own distinctive worldview (basically liberal Christianity without Christ), their own common educational experience, their own shared values and assumptions (social psychologists call these WEIRD — for Western, Educated, Industrialized, Rich and Democratic), and of course their own outgroups (evangelicals, Little Englanders) to fear, pity and despise. And like any tribal cohort they seek comfort and familiarity: From London to Paris to New York, each Western “global city” (like each “global university”) is increasingly interchangeable, so that wherever the citizen of the world travels he already feels at home.
