Hmm... wish I had the exact original handy to mis-quote ...

Is this the one you mean? First they came for the Communists, and I didn't speak up, because I wasn't a Communist. Then they came for the Jews, and I didn't speak up, because I wasn't a Jew. Then they came for the Catholics, and I didn't speak up, because I was a Protestant. Then they came for me, and by that time there was no one left to speak up for me. by Rev. Martin Niemoller, 1945.
