Historians are incapable of second guessing Hitler's inner thoughts 
There may be some who believe that historians are capable of deciphering Hitler's inner thoughts, i.e. Hitler's religion.  This is ignorance and stupidity.  They write things such as "while historians such as Ian Kershaw, Joachim Fest and Alan Bullock agree that Hitler was anti-Christian".  They do not even provide quotes of Ian Kershaw, Joachim Fest and Alan Bullock saying that Hitler was anti-Christian.  All they are saying is trust us in our opinion the opinion of Ian Kershaw, Joachim Fest and Alan Bullock is that Hitler was anti Christian.  A far better procedure is to rely on the opinion of Hitler himself as to his religion.
