It doesn't really bother me that much. Even the the published Diary of Anne Frank,  was not a "diary", but consists of a substantially revised compilation of her earlier writings. Not a hoax, but not really a "dairy" either. But who cares?  I think  we're to pedantic about "reality". My idea of what's real (fact) may not be the same as your's, but we can still live quite happily together.

Edit - The WMD in Iraq were once a "fact", we saw the diagrams and aerial photos of them, after the invasion they then became "fiction". We basically believe what we want to and that's just human nature.
