“Liberating tolerance, then, would mean intolerance against movements from the Right and toleration of movements from the Left. As to the scope of this tolerance and intolerance: ... it would extend to the stage of action as well as of discussion and propaganda, of deed as well as of word. The traditional criterion of clear and present danger seems no longer adequate to a stage where the whole society is in the situation of the theater audience when somebody cries: 'fire'. It is a situation in which the total catastrophe could be triggered off any moment, not only by a technical error, but also by a rational miscalculation of risks, or by a rash speech of one of the leaders. In past and different circumstances, the speeches of the Fascist and Nazi leaders were the immediate prologue to the massacre. The distance between the propaganda and the action, between the organization and its release on the people had become too short. But the spreading of the word could have been stopped before it was too late: if democratic tolerance had been withdrawn when the future leaders started their campaign, mankind would have had a chance of avoiding Auschwitz and a World War.”
