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)
