Bara,
Seriously, people might have their own motivations for saying what they say, but a story like Nasser's, though some parts of it might be objectionable to some, is the story bodybuilding fans have been waiting forever for. I know when I used to read muscle magazines the first thing I would look for was something real and intriguing and not just your average "I was skinny so used weights to bulk up" piece.
You might not like Nasser but you have to admit his book wil be a bodybuilding first based on what he is willing to discuss.
