From the headline: David Horowitz’s memoir Radical Son, in which he ponders how and why his Jewish parents became members of the Communist Party U.S.A., and thus idolators in the totalitarian personality cult of a mass murderer named Josef Stalin. Horowitz recognized the cultural roots of this and discussed it in the context of tikkun olam. As I wrote in February 2011:

Tikkun olam is a rabbinical concept that might properly be translated as “for the public good,” but which in the modern era has been politicized by many on the Left, so that it is indistinguishable in their interpretation from “social justice.” Most famously, Michael Lerner — a 1960s anti-war radical who once led an SDS splinter group called the Seattle Liberation Front — named his magazine Tikkun.
