Interesting, as an atheist I think the same way too, there is a greater probability that you are insane that there is for a Personal God existing, but I am not sure my attitude is the best, I mean, even if there was a real God and he came before me, I would count myself insane. i.e., Nothing can trump this argument if you believe in this, sounds a bit close minded to me, I don't know what the right way is either.
