The Hitler - Coulter quote quiz is brilliant. I did assign 11/14 correctly, but I relied on writing style, reference to Americans, etc. If not for those tricks I'd have been guessing randomly.
Coulter's language, like so much of American hate radio, really is eerily similar to Hitler's.
It's useful to try the quotes while substituting "Jew" or "Bourgeois" or "Intellectual" or "Intelligentsia" for "Liberal". Works well with any of those.
