Why do those who want to discredit the authenticity of what Anne Frank wrote (it wasn't a diary like a 365 page diary from WH Smith's - it was loose leaves and an autograph book) nearly always seem to have filled their minds with websites like those that come from the neo-Nazi/Hitler was misunderstood/no ovens at (insert name of camp)/Zyklon B was only ever a pesticide etc. end of the spectrum?
It's as if they think that by saying that there were ball point pen annotations on two loose leaf sheets of paper or that a vacuum was used at 12.30 daytime that the whole Holocaust falls apart. That everything at Nuremberg was a falsification against those poor Nazi's who deserve so much sympathy.
I perfectly understand the points that her father Otto may have edited things out as he and his first wife may not have been cast in a good light and that he made money by having it published. Fair enough.
But I'm happy with the work that the Dutch Institute for War Documentation did in 1986 to prove the diary authentic as to when it was written and by whom.
I'll be drawn into the silliness about the vacuum cleaning schedule and quote from the work done by Paul O'Donnell, Professor of English at the University of Lethbridge in Canada.
"... Anne is careful to note throughout her diaries that the vacuum cleaner is only run when nobody is in the building - either at night, or during the lunch hour when everybody but Otto Frank's most trusted employees are away ..."
Look at the context. The type of building, the country (Holland was well known for "hiding" Jews from the hated German invaders, almost in open sight if they were fairer skinned, more hidden if they were not, like the Franks. Unlike Catholic Eastern Europe where Germany was often preferred to Russia and where a vein of anti-Semitism ran deeper than in England, Belgium, Holland, Denmark and Norway.)
The hiding place was "over the workshop" as in the property was a place of business a fairly noisy place due to spice mills and food processing. River traffic added to the noise. Chimneys exhausted boiler smoke and burnt waste product. The secret annex was at the back hidden by tall 4 storey buildings and apartments on all sides.
It would be difficult to distinguish where the noise of a vacuum in an apartment building might have been coming from. In the unlikely event that a passerby heard a vacuum then if he noticed it at all he would just look in the direction of a 4 storey apartment block come factory and just put it down to normal noise in a city location.
As ex-JW's and exiting-JW's we should be used to drilling down through falsehoods to get to what rings true. But if we let ourselves down by lazy thinking or let our prejudices get in the way we will not get beyond scratching the surface.
