We all need to get really good at reversing Pascal's Wager, but I'm beginning to wonder that it may not even work.  When we're asked why we don't believe in God, our answer is "lack of evidence."  When we try to make believers see that "the reason you reject all the other gods except your own is the reason I reject them all", their reasoning may not even work on this level.  I think perhaps for many, they operate on the mode of "I don't believe in the other gods because MY God tells me so."  So we're up against a wall.  Maybe the only defense for Pascal's Wager is "Yeah.  See you later.  I'm not worried."
