My friend and colleague Anthony Cody tells the story of his family’s travails during the McCarthy era and links it to events of the present day.

Not long after I first met Anthony, about five years ago, he briefly summarized the story of his parents and the hardships they endured because of McCarthyism. As a historian, I urged him to write about it. The events of the past week provoked him to do so, especially when he heard a Trump surrogate speak of the World War 2 internment camps for Japanese-Americans as a precedent for dealing with suspicious Muslims. Those camps were eventually ruled unconstitutional, and those who were interned were paid reparations, which were certainly inadequate to the loss of their freedom and the humiliation of being jailed because of their origins. But obviously the Trump surrogate didn’t know the facts.

Anthony’s parents were supporters of human rights and civil rights at a time when it was dangerous to be leftists. They fled the country and moved to Mexico to avoid being forced to testify before the infamous House UnAmerican Activities Committee in 1950.

When it was safe to return, in 1954, they moved to Berkeley and opened Cody’s Bookstore, which became a celebrated mecca for student activists and radicals of all stripes.

Fast forward to the present and we have a President-elect who was mentored by the infamous Roy Cohn, a protege of Joseph McCarthy. Cohn was an unscrupulous and unethical lawyer who was eventually disbarred. Trump was a close friend of Roy Cohn, who mentored him. According to profiles of the two, Cohn taught Trump to meet every challenge with “attack, counterattack, and never apologize.”

Anthony’s parents’ lives are a part of American history that we should study and learn from. One thing we can learn is that bad things don’t last forever. In the presence of injustice, we must stick to our principles and resist, as his parents did. It is resistance that eventually prevails, not passivity.
