First they came for the communists, and I didn’t speak out because I wasn’t a communist.
Then they came for the trade unionists, and I didn’t speak out because I wasn’t a trade unionist.
Then they came for the Jews, and I didn’t speak out because I wasn’t a Jew.
Then they came for me, and there was no one left to speak out for me.
— Pastor Martin Niemöller
