Query: You have to be a fundamentalist x-tian to read this.

He assumes that this Satan exists in the same way the x-tians defined it 2000 years ago . . . He keeps blabbering on about this Satan. I wouldn't mind if his intentions was to save humankind, but this looks like a fundamentalist x-tian who is out to make money . . . He has done a great deal of research on the subject though, still I would say you have to be a x-tian to actually gain anything from this book.
