Let me guess, you are of a younger generation. I am old enough to have heard first hand accounts of not only those that saw the atrocities, but also those that lived it.Nobody is denying bad things happened.
We are discussing war propaganda and financial scams.
Turn off the Boob Tube and go read books to educate yourself.
It seems as when those that were around during those times disappear, it is much easier to deny it.
