Martin Niemoller

"First they came for the Jews, and I did not speak out - I was not a Jew
Then they came for the Communists, and I did not speak out - I was not a Communist
Then they came for the trade unionists, and I did not speak out - I was not a trade unionist
Then they came for me - and there was no one left to speak out for me."

- Martin Niemoller, theologian and pastor imprisoned by Nazis in 1937
