There is a lot between "denial" and "6 million gas and ovened, funiture from body parts, soap, and death rollacoasters". The wild exagerations only serve to increase doubt rather than disuade it. The National Socialists like the Communists and other allied and axis powers are guilty enough of plenty of horrendous crimes. There is no reason to exagerate or fabricate extra maniacal deeds. Monopolizing victimhood in WWII is itself narcissistic and disgusting.
