First they came for the communists, and I did not speak out--

because I was not a communist;
Then they came for the soc-ialists, and I did not speak out--

because I was not a soci-alist;
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 out for me.
