On his new video (https://goo.gl/I1D5VC) Khamenei merely states a fact: many (central) European countries have laws that make illegal to question the holocaust. Now it is true that, denying the holocaust is almost impossible, as the Nazis had records and footage that was confiscated by the Allies. However, if Ann Coulter can- exercising her freedom of speech- promote hatred against minorities, yet sell millions of books, then why is there such a stigma against those who try to deny the Holocaust?
Also let’s not think that Khamenei’s critique on as the beginning of new tensions between Persia and the West. On the contrary, Europe is now investing billions in Iran http://usat.ly/1SM443J
