In exchange for being allowed to leave Austria in 1938, Sigmund Freud was required to sign a document showing that he had been treated well by the incoming Nazis - he signed adding "I can most highly recommend the Gestapo to everyone."

His sarcasm was, apparently, lost on the assembled thugs at the time and it seems their followers here are still demanding that we ignore their poisoned theories and only say nice things about them. It wasn't acceptable then and it isn't acceptable now.
