First they came...

I have been browsing history about WWII this past weeks.
Here I share a poem I encountered.
This poem is cited from Wikipedia:
First They came...


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."

attributed to Pastor Martin Niemöller (1892–1984)
