@ Mario de Monti
I'm afraid you're beating an "invisible" horse here. Apparently you and I have seen a lot of documentaries about what was actually going on in the concentration death camps.
As for the others participating in this debate, I'm really not sure. I suggest they should first watch "Judgement at Nuremberg
" (starring William Shatner) containing graphic, original films and then "Schindler's List". Then, if they still feel it's a subject meriting whatever humor you can think of, let them speak their minds.
