In June 1977, a group of white anti-racist activists received an alarming letter from an inmate at a New York state prison calling for help to fight the Ku Klux Klan’s efforts to recruit prison staff and influence the people incarcerated. Their response was to form the first chapter of what would eventually become a powerful, nationwide grassroots network, the John Brown Anti-Klan Committee, dedicated to countering the rise of the KKK and other far-right white nationalist groups. ‘No Fascist USA!’ tells the story of that network, whose efforts throughout the 1980s—which included exposing white supremacists in public office, confronting neo-Nazis in street protests, supporting movements for self-determination, and engagement with the underground punk scene—laid the groundwork for many anti-racist efforts to emerge since. Featuring original research, interviews with former members, and a trove of graphic materials, their story offers battle-tested lessons for those on the frontlines of social justice work today.
