If there were a measuring device for the intensity of collective emotions, it would currently show peak values: In political debates, anger, hatred, and fear have replaced rational arguments and mutual consideration in many places. Uffa Jensen traces the origins of anger politics back to the 19th century and explains how such feelings of rejection operate. It becomes clear that emotions particularly flare up in conflicts regarding societal others such as refugees, Muslims, or Jews, and are deliberately instrumentalized. From the historical connections between prejudices and emotions, Jensen derives strategies that we can use to confront the current wave of political fury.
