There aren't many difficult steps in refuting Pascal's wager, and I dont' think there's be much disagreement on it here.
The refutation of PW, in short, is this: it infers high utility based on a very complex (and thus highly-penalized) hypothesis, when you can find equally complex (and equally well-supported) hypotheses that imply the opposite (or worse) utility.
(Btw, I was one of those who voted you down.)
Again, is it the argument that is wrong, or Pascal's application of it?
(Can you confirm whether you down-voted me because it's off-topic and inflammatory, or because I'm wrong?)
It has been claimed on this site that the fundamental question of rationality is "What do you believe, and why do you believe it?".
A good question it is, but I claim there is another of equal importance. I ask you, Less Wrong...
What are you doing?
And why are you doing it?
