“The most intelligent of the Nazis, the legal theorist Carl Schmitt, explained in clear language the essence of fascist governance. The way to destroy all rules, he explained, was to focus on the idea of the exception. A Nazi leader outmaneuvers his opponents by manufacturing a general conviction that the present moment is exceptional, and then transforming that state of exception into a permanent emergency. Citizens then trade real freedom for fake safety.
Dissidents of the twentieth century, whether they were resisting fascism or communism, were called extremists. Modern authoritarian regimes, such as Russia, use laws on extremism to punish those who criticize their policies. In this way the notion of extremism comes to mean virtually everything except what is, in fact, extreme: tyranny.”
