"First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the trade unionists, and I did not speak out—because I was not a trade unionist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me."
—Martin Niemöller

His mistake was his belief that the Nazis were good Lutherans rather than Jungian Hindu UFO mystics.
"Martin Niemöller (1892–1984) was a prominent Lutheran pastor in Germany. In the 1920s and early 1930s, he sympathized with many Nazi ideas and supported radically right-wing political movements. But after Adolf Hitler came to power in 1933, Niemöller became an outspoken critic of Hitler’s interference in the Protestant Church. He spent the last eight years of Nazi rule, from 1937 to 1945, in Nazi prisons and concentration camps."
