I am looking for any official (mainstream) explanation for the different handwriting styles found in Anne Frank's writings.
They say that the ballpoint pen thing was only a couple of loose pages with notes, and not any of the diary content, and none of the notes in ballpoint pen are printed in any of the editions (because it's not part of the diary).
The 1980 forensic study at least shows that the handwriting was consistient accross the "diary" itself.
But what about the very different handwriting styles in, for example pic related, and in the Iowa letter? Is there any official response?
I just want to make sure the redpills I'm eating are the genuine article, and not easily rebuffed. It's very embarassing and counterproductive to redpill normies with things they can find plausible counter arguments for.
