When my dad was stationed in Germany in the late 50's (when I was still a kid), we went to a concentration camp. Even today, I still get chills down my back recalling the sensation of pure evil I felt there.
The moonbats can make whatever noise they want about concentration camps and the Holocaust - it still doesn't make them right, it just makes them moonbats.
History is filled with the pronouncements of nutjobs. We still have people who believe that the earth is flat and that Columbus didn't discover America.
Just keep passing the popcorn and consider the source - it's entertainment.
