What you're saying is 'Has a historian the right to offend?' and the answer is very definitely, yes.
Interview with John Humphrys on The Today Program (23 December 2006)
A man for whom Hitler is something of a hero and almost everything of an innocent, and for whom Auschwitz is a Jewish deception.David Irving
The Nazis quite clearly killed millions of Jews...David Irving
The interesting questions are what did Hitler know, did Himmler conceal it, did he keep it from Hitler, where was the killing done, was it Auschwitz, was it the Reinhard camps and that's what people are frightened to research, because they go to prison for it.David Irving
I don't think there was any overall Reich policy to kill the Jews. If there was, they would have been killed and there would not be now so many millions of survivors. And believe me, I am glad for every survivor that there was.David Irving
