Fritz Sauckel Quote
Only Communists and Social Democrats who acted against the state were incarcerated. Most of the Communists and Social Democrats I had known became Nazis later. Only those who were doing anything against the state were thrown in concentration camps.
To Leon Goldensohn, February 9, 1946, from "The Nuremberg Interviews" by Leon Goldensohn, Robert Gellately - History - 2004.
