first they came for the communists, but i was not a communist so i did not speak out. then they came for the socialists and the trade unionists, but i was neither, so i did not speak out. then they came for the jews, but i was not a jew so i did not speak out. and when they came for me, there was no one left to speak out for me. dietrich bonhoeffer 1906 - 1945
