An artificial date; no date would suffice. Every day is Yom HaShoah. It went on for years. No matter how many times, how many stories, in person and in media, there is nothing but head shaking, grief, sorrow, and radical awareness that there is nothing so awful it can’t happen. This was a political system, and a religious system. Yes. The eminent Shoah historian, Saul Friedlaender, aptly discusses the Nazis’ “redemptive antisemitism,” distinct from other versions. It was a mystical, religious system; a form of fundamentalism. My goal here, and today of all days, is not to study them but to learn from the dangers inherent in certain kinds of thinking and types of organization — parties, governments — that come from that.
