About Hitler, Stalin and Pol Pot?

“Such regimes are dogmatic to the core and generally give rise to personality cults that are indistinguishable from cults of religious hero worship. Auschwitz, the gulag, and the killing fields were not examples of what happens when human beings reject religious dogma; they are examples of political, racial and nationalistic dogma run amok. There is no society in human history that ever suffered because its people became too reasonable.” -Sam Harris
