Belgium: Holocaust memorial patron is gas chamber negationist!

Drawing lifted from a Holocaust-
denial Portuguese blog

Belgian Jewish on-line magazine Regards reported an antisemitic incident which took place at a Brussels restaurant.

A diner overheard people at the table next to hers calling Jews a "filthy race" and denying the existence of gas chambers.  The lady and her husband drew a swastika on a piece of paper and pinned it above the table where the group of friends were sitting.  They were greatly amused, started laughing and explained that they had  first-hand experience of the war and contested the existence of gas chambers. 

An investigation revealed that the author of the remarks, Mr Jacques Engels, was a member of the resistance during the war and that he is a prominent member of the World War II memorial Kazerne Dossin.   He is a collector of war documents which he entrusted to the museum.  But it turns out that he denies the existence of gas chambers!

A question arises: how can someone be an active supporter of a museum/memorial dedicated to the Jews deported from Belgium and murdered in the gas chambers of Auschwitz-Birkenau, and at the same time deny the existence of gas chambers?

Mr Engels has since explained that his words had been taken out of context. People who know him have indicated that it is not the first time that Mr Engels, who is now in his 90s, has engaged in Holocaust-denying.
