There seem to be several versions of the saying out there used by the Right and the Left. The version I always heard was on libertarian sites: "First they came for the Jews, and I was silent because I was not a Jew. Then they came for the guns, and I was silent..." Ending with, "When they came for me, there was no one left to speak out."
But it appears it started as a saying against the Nazis.
Well... I just did a little too much research on that one. :-0 Back to work...

First They Came for the Jews
First they came for the Jews
and I did not speak out
because I was not a Jew.
Then they came for the Communists
and I did not speak out
because I was not a Communist.
Then they came for the trade unionists
and I did not speak out
because I was not a trade unionist.
Then they came for me
and there was no one left
to speak out for me.
