First they came for...

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.

– Martin Niemoeller (1892-1984)
