Yes, I agree. "Nit picking" is a good description.
I imagine that holocaust deniers avoid "over all" views because it makes their own claims ridiculous. For example, I can never get a holocaust denier to explain what the Secret Jewish conspiracy is?
If the first eyewitness reports concerning mass executions start appearing in 1942 in Poland by escapees, then how does Adolph Eichmann claim the same events happened in an Israeli court in 1960? There are around a hundred eyewitness reports from both Jewish slave workers, Poles, Ukrainians and Germans saying the same thing over decades.
Who exactly do Holocaust denier claim is coordinating the instructions telling these eyewitnesses what to say if they are all fake (according to holocaust deniers)? Why would German SS officers follow instructions from a secret Jewish organisation? If the British army supposedly beat up Hoess to make him confess, then is not the British army part of this secret Jewish conspiracy, as they had to share the same eyewitness information?
The whole holocaust denial movement is just silly. Now that Treblinka is being excavated, I imagine the few remaining deniers will become even weirder in their claims.
