@FBM,
Derren Brown makes his career as a magician/illusionist, (I think he actually describes himself as a mentalist) and he's very good. His shows are very good and well worth watching. I was always a fan, that is until my daughter bought me one of his books for Father's Day. I thought it was going to be a really good read about the life of a professional magician, maybe a little bit about how certain things were done, not that I was expecting him to give away all his tricks mind you, maybe some of the more well known illusions, like a lot of magic books.
Not at all, it was just one long rant about why there is no God, (and there was no hint of that in the blurb on the back.) I felt totally ripped off, and more importantly so did my daughter. One thing he wrote did stick out though, he used to be a very evangelical Christian, and he thought that would surprise his readers. It didn't surprise me in the slightest, he's quite ardent and fanatical, he just changed the object of his fanaticism. Instead of thinking he has a mission to turn everyone into Christians he now thinks he has a mission to turn everyone into Atheists, and I suspect his homosexuality may have something to do with his conversion.
Like a lot of people who bought his book in good faith, I think he's got a bit of a brass neck talking about charlatans because his book was nothing at all like it was described in the blurb. By all means he should be allowed to write a book like that, but he should be honest enough to say what the book is really about, instead he used the same underhand tactics of the TV evangelists he so despises.
I can't watch his shows any more, I just find him totally dishonest.
