It is entirely possible that the account of the author is muddled and/or embellished. They were forced to take drugs for much of the experience and were children after all.

Reminds me of Haley's "Roots", that was presented as fact when it was fiction.
And "A Million Little Pieces" by James Frey.

If you live in a world of black and white where you lack the capacity or compassion to consider the context of a person's experience, sure. That would require the kind of mindset that would completely reject the account of a Jimmy Saville victim because the he didn't visit the place they alledged an abuse took place until 2 years after the year they originally said.
