        Obviously false, as explained in my previous posts, both for a
theory like QM with initial conditions as free parameters, and even for a
theory in which there are no free parameters as explained in my last post.

        The above paragraph makes no sense to me.

        This is the part that got me riled up. Pascal's bet is the height
of stupidity. I'd rather live as an atheist and go to hell than spend an
eternity kissing up to a god so evil and self centered that he'd send me
to hell just for not believing in him when I had no evidence.
