Howard Zinn in The Progressive:
Fifteen years ago, when I was teaching at Boston University, I was asked by a Jewish group to give a talk on the Holocaust. I spoke that evening, but not about the Holocaust of World War II, the genocide of six million Jews. It was the mid-eighties, and the U.S. government was supporting death squads in Central America, so I spoke of the deaths of hundreds of thousands of peasants in Guatemala and El Salvador, victims of American policy.
My point was that the memory of the Jewish Holocaust should not be circled by barbed wire, morally ghettoized, kept isolated from other atrocities in history. To remember what happened to the six million Jews, I said, served no important purpose unless it aroused indignation, anger, action against all atrocities, anywhere in the world.
