Now they're doing it a lot with Trump and Hitler. Just google and you'll find plenty.
And of course the irony of all this, as the quibcag says, is that when we find out that some such quote was actually from Hitler, or Franco, or Pinochet, it leads us not to reject the idea — it already sounded good to us — but to think maybe we had the wrong idea about Hitler or Franco or Pinochet in the first place.
And this calls to mind the Marvel Comics stunt recently, where one of their supervillains, the Red Skull, is shown giving an anti-immigrant speech, proving that immigration restrictionists are Nazis. The latest opinion on all that here — Caution: F-word language.
Quibcag: I photoshopped this, putting the Red Skull's face over that of a girl from K-On! (けいおん! Keion!)
