If you research a bit of the Holocaust you will soon learn there is a lot of weird things going on in the story that doesn't really make much scientific sense. Take a look at this documentary that covers 1/3 of the concentration camps: www.onethirdoftheholocaust.com While I do believe the Holocaust happened and it was a terrible thing, I also realize that people tend to exaggerate their stories.

Unfortunately, most people have such an emotional reaction against questioning anything related to the Holocaust they completely give up reason and instead become blind to any scientific argument.
