One quick note before I go to bed. I agree that this stuff doesn't represent a critical hit on Christianity, because as I think I've said already somewhere in this discussion I think annihilationism is certainly a viable option for Christians (even if they're committed to a pretty conservative outlook) and largely sidesteps any complaints about hell; and universalism is probably viable too, and does away with such complaints entirely.

On the other hand, I *do* think these considerations render belief in eternal torment entirely untenable. You are, of course, welcome to disagree.
