Which means absolutely nothing. I can heavily footnode and reference a text that would talk about how it is possible to walk to the moon and back, but sadly, adding footnotes or references does not make things come true.  
 I for one don´t see anything wrong with this article. It clearly shows that the book is a non-academic book written by somebody with an agenda. Nothing wrong with that, but nothing special with that either. If you lack the talent or training the book you write will reflect this, and subsequently the wiki-article about the book.
