I already have these three covered:

Ex-NSDAP voter: "I voted for Adolf Hitler three times thinking he was going to be the peace candidate. Boy, was I wrong."

KPD voter: "Hitler is the worst Reichskanzler we've ever had."
NSDAP voter: "Lol, you have clear case of HDS."
KPD voter: "What's HDS?"
NSDAP voter: "Hitler Derangement Syndrome."

SocDems: "I really despise the Rabbis' influence over the Jewish people, but what the Nazis are doing to the Jews right now is bad."

Judging by what people are saying now, Hitler's supporters probably said things like

"If the jews just complied with the law they'd have nothing to worry about"

And "are the death camps in the room with us now?"

Real Talk: Germany's major far right party (AfD, "Alternative for Germany") and parts of the major conservative party (CDU, "Christian Democratic Union") are literally doing this type of quote farming, to experiment what they can get away with or to create attention. If you use those without critical distance, this is often even illegal ("Incitement of the masses", "Use of hallmarks of unconstitutional organisations" et cetera).
