How new fascism operates

Historian Marci Shore doesn't hesitate to use the word 'fascism' to describe the present moment. The former Yale professor left the U.S. after President Trump was re-elected. She now teaches at the University of Toronto and tells her students why "we shouldn't fetishize" the term. Shore argues concepts and terminologies born from history like fascism is how we process the world, but it's critical we allow for today's nuances and differences. This podcast includes Marci Shore in conversation with IDEAS host Nahlah Ayed and Shore's lecture “Thoughts From a Post Truth World," part of the series “Democracy in Peril: A Way Forward Against Authoritarianism," organized by the University of Manitoba, and the Canadian Museum for Human Rights in Winnipeg. Marci Shore is Chair of European Intellectual History at the Munk School of Global Affairs & Public Policy at the University of Toronto.
