In 2004 the now extinct original RODOH forum hosted a debate, known as the "Scholar' Debate", between the "Negationist Team", led nominally by the late Dr. Robert Countess and effectively by Scott Smith, and the "Veritas Team", led by Stephen Mock and including Sergey Romanov and myself.
The topic of the debate was the following:
"Resolved, at Auschwitz/Birkenau between 1941 and 1944, a) people were killed in homicidal gas chambers employing Zyklon B, and b) this killing claimed hundreds of thousands of victims."
The submissions of this debate are being reconstructed in the section "Scholars Debate" (2004 + under re-construction) of the new RODOH forum.
The opening statement of the "Veritas Team" has already been posted.
