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.
The actual truth : None of those people on that list will stick up for you unless you're one of them. Every one of them will let you hang out to dry, and encourage your arrest for whatever. They only tell you this to assure THEIR freedom. When it's you facing anything from ostracization all the way to the gallows, they'll be the biggest 2-faces you've ever seen, and spit on you as you're cancelled for some politically incorrect "violation". Don't expect any reciprocation by them if you speak out for their "right to say it" "or be it" or whatever.
Conclusion : One of the WORST quotes of all time, and not to be trusted
