An era of paranoia, the pull of radical politics, the way in which an entire society can fall under the sway of a fever, and how that fever eventually breaks. These themes made up one of the darkest periods of modern American History: The era of McCarthyism and the Red Scare. This week historian and journalist David Maraniss discusses his new book “A Good American Family”, that excavates the story of his own leftist parents as they lived and raised a family during the Red Scare. Maraniss reconstructs his parents’ story by using memoir, archived materials, and corroborating accounts to piece together his family’s own experience. It is a story that gives insight into the experience of those targeted during the Red Scare and themes that we are still seeing and grappling with now.
