America’s cultural revolution, launched in the late 1960s and never quite stopped, has always been a Janus-faced phenomenon. One face was the Boomers’ euphoric hedonism and disregard for the moral guardrails of tradition and authority … The other face was dour and vicious, masking a raw hunger for power under a preening moralism. This side of the revolution could be detected in many countercultural phenomena, not least the juvenile activism and noisy readiness for ­violence that were such conspicuous features of the age. Today, the revolution is presenting this second face to a complacent America.
