Nostalgia is a powerful political tool. Wielding nostalgia for a bygone era — one that is invariably mischaracterized — is a favorite weapon for fascist movements (Make America Great Again), harking back to a time before their nation was “polluted” by malign forces. In the United States, such nostalgia none-too-subtlety appeals to white Christian nationalism. Even in a more benign form (e.g., “Politics didn’t used to be so mean,” “Remember the days of bipartisanship?”) plays on faulty memories. If you really go back to study U.S. history, you would find two things: The past was worse, and conflict has always been the norm.
