Why speak out?

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.
