For me, the clue that the six million figure might be suspect is that six million is a very popular number when referring to Jews. It seems to be used in the same way that many people use "five minutes". When someone says they will be five minutes that are not stating a delay of exactly 300 seconds rather that they are implying a short time.

Six Million could just mean "a lot" or "a large number". It has special significance to Jews because they believe that six million Jews will need to die before that achieve their Israel.

As evidence I propose this list entitled: Two hundred ''Six million Jews'' allegations from 1900-1945.

This is a video saying much the same thing. Interestingly(!), I have links which I have saved to other videos which all say the same thing but are now removed. It is almost as if someone is trying to hide the truth.
