For having a better idea on the official story, please see here :
David Irving is a Hitler supporter and said many times the Holocaust was the work of others and Hitler played no part. This is a very sensitive area, David Irving went as far as questioning the gas chambers at Auschwitz. Yes I have read a couple of his books and I wonder if David Irving has read Commandant of Auschwitz by Rudolf Hoess.
