The old never really understand the young, especially in times when the paradigm is changing. The old looked on with dismay during the nineteen-sixties and seventies when so many Boomers rejected traditional morality and established social roles, inaugurating the Age of Aquarius with a utopian belief in the power of universalism to overcome tribalism. For the post-war idealists, flowers of tolerance were the answer to the guns of hatred that made the twentieth century so hellish for so many.
The post-war generations came to believe that World Wars I and II were the result of authoritarian white maleness. Central European theorists such as Theodor Adorno and Herbert Marcuse led the intellectual movement to convince young Westerners that this was the case and were very successful. Those ideas fuelled the New Left movement that took over the campuses and the hippie movement that took over the culture.
