Fratelli Tutti §156
Fratelli Tutti: On Fraternity and Social Friendship
156 In recent years, the words “populism” and “populist” have invaded the communications media and everyday conversation. As a result, they have lost whatever value they might have had, and have become another source of polarization in an already divided society. Efforts are made to classify entire peoples, groups, societies and governments as “populist” or not. Nowadays it has become impossible for someone to express a view on any subject without being categorized one way or the other, either to be unfairly discredited or to be praised to the skies.
