No one was left

First they came for the Socialists, and I did not speak out because I was not a Socialist. Then they came for the trade unionists, and I did not speak out because I was not a trade unionist. Then they came for the Jews, and I did not speak out because I was not a Jew. Then they came for me, and there was no one left to speak for me.

—Martin Niemöller (1892-1984)
