I'm not going to engage in a religious debate beyond saying that you are wrong, we don't believe that you go to Hell if you aren't a Mormon. Do dig out a copy and reread those verses, then see that in context he is addressing people who belonged to the church, people who were rebelling against God and unrepentant. We do not believe that being baptised into the church gaurantees you a place in Heaven, and that all non Mormons go to Hell. Come to think of it, I'm not even sure you know what we mean by heaven and hell.
As for baptism for the dead, you don't really know what our doctrine behind that is either. Redemption isn't FOISTED on anyone, as baptism does NOT ensure redemption. Be nice if it were that easy.
All that baptism for the dead does is give them an opportuntiy. Since you seem to know so much about us, you should know that we believe that freedom of choice extends beyond the grave and that the mere undertaking of an ordinance guarantees nothing.
I don't insist that you agree with me (don't really care even), but at least try to understand how WE see things. Does marvels for tolerance, though perhaps you don't think that extends to religious people. I try to extend the same courtesy, of understanding, to any faith, as well as to atheists.
Before you start on about how I said I wouldn't press, remember that you brought up the last points.
