Ask him this question? Is the haulacauat considered one of the worst genocides in history and did the allies know about it and try to stop it? If he agrees then ask him to do these things... 1. Ask him why Winston Churchill who wrote a very extensive history and biography of ww2 almost completely fails to mention the haulacaust in any meaningful way. He should have known more then any one about how bad it was. 2. Ask him to look up any encyclopedias up to 1970 and try to find any mention of the haulacaust, or 6 million or austwitz or death camps there is nothing until about 1973 when the lying machine started 3. Ask him if the transcripts of the decoded messages that Germany had ever mentioned anything related to death camps or jews... the Germans had no clue they were being recorded and never mention anything close to resembling the halacuaust
