OTTUMWA, Iowa— Yesterday, America observed the 75th anniversary of D-Day. Some spent the day with local World War II veterans. Others visited military cemeteries to honor those who made the ultimate sacrifice. But all Americans held fast to the central tenet of the day and our nation as a whole: calling people we disagree with Nazis.

The tradition first began in Berlin, at the Reichstag in 1933. Legend has it that when President Paul von Hindenburg appointed Adolf Hitler Chancellor of Germany, a member of parliament remarked, “Are you kidding me? That guy is literally a Nazi.” Since then, the term has morphed to include liberals, conservatives, and the civilians who work at CIF.
