you must wager because if god exists god does not care if you  
 dont believe in god.  If god does not exist, you still eventualy 
 have to come clean to yourself on what you believe.  Agnostics:you 
 have either decided to believe and are looking for what to believe, 
 or you have decided against belief and look for reasons why. these states of mind are inevitable, psychologicly you must wager to stay sane.  when he says you have no choice, he truly believes that belief, un-belief, or whatever are conditions of your physical/spiritual self, like breathing or your heart beating.  If you say you won't wager, he would call you a liar or at least maybe you don't remember doing it, but anybody with or without faith has had to decide.
