The "preening silliness" of the left's obsession with "cultural appropriation"

George Will:

... The hysteria du jour, on campuses and elsewhere, against “appropriation” illustrates progressivism’s descent into authoritarianism leavened by philistinism. This “preening silliness” — the phrase is from the Federalist’s David Marcus — is by people oblivious to the fact that, as Marcus says, “culture blending is central to the development of, well, everything.”

... Listening to Radio Luxembourg late one night, teenaged Keith Richards heard “Heartbreak Hotel,” and “when I woke up the next day I was a different guy.” Bob Dylan, a freewheeling cultural appropriator himself, said, “Hearing Elvis for the first time was like busting out of jail.” Those who would wall off cultures from “outsiders” are would-be wardens.
