In Germany, 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 but I didn't speak up because I was not 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 nobody was left
to speak up.
-- Martin Niemoeller, German Lutheran Pastor, Dachau, 1944
