They came first 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 trade unionists, and I didn't speak up because I wasn't a trade unionist.

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 no one was left to speak up.

Martin Niemoller, German Protestant Pastor, 1892-1984
