Sad to see you bogged down in the concepts of fact and fiction, and the distinction between the two, that applies to normal everyday discourse and to scientific research as well, but are wholly out of place with discussion related to the holohoax.
The 'testimony' of holohoax survivors is not to be evaluated with the misplaced notions of fact and fiction, instead it is to be interpreted as a cry from the heart, the voice of the universal suffering, that touches deeper truths than can be reached by others.
As a result, we have to train our ignorant ears to properly hear what the hoax survivors are telling us. That's not what I claim, but it is what the goyim have resorted to in explaining the obvious and degenerate lies of every holohoax survivor ... check out for example respected Austrailian historian Inga Clendenen.....

Clendenen explains, in her book 'Reading the Holocaust', that ....
"We have to train our ignorant ears to hear those communiques from the underworld. The voices we will hear find their context within a vast silence: the multitude of the dead. It is almost impossible to fathom the depth of the silence, to remember that behind the shoulder of every individual who survived the camps stand a thousand who did not."
