Old news but I found it oddly fascinating:
http://www.theguardian.com/world/2013/may/03/david-stein-cole-holocaust-revisionistOver the past five years Stein's organisation, Republican Party Animals, drew hundreds to regular events in and around Los Angeles, making him a darling of conservative blogs and talkshows. That he made respected documentaries on the Holocaust added intellectual cachet and Jewish support to Stein's cocktail of politics, irreverence and rock and roll.
There was just one problem. Stein was not who he claimed. His real name can be revealed for the first time publicly – a close circle of confidants only found out the truth recently – as David Cole. And under that name he was once a reviled Holocaust revisionist who questioned the existence of Nazi gas chambers. He changed identities in January 1998.
