Ed: You seem to forget that it is atheists like Loftus who attempting to prove something here. So if, as you say, the discussion proves nothing and solves nothing, the theist wins.
Theists typically are not satisfied with a fideistic response to the problem of evil, that all the suffering is just God's will and that we should accept the "because I said so" theodicy. It is absurd to suggest, as you do, that this is a test for Christian orthodoxy.
It's something like evolutionary biologists. An evolutionary biologist does not necessarily think that evolution is disproved if there is a gap in the fossil record they can't explain. But if they couldn't explain anything, they's be in trouble. Christian reflection on suffering can perhaps explain a good deal of human suffering. Most theists at the same time realize that their best explanation efforts fall short of explaining all evil, but nevertheless they think that the force of what atheists think is an overwhelming argument for atheism is far from what the atheist supposes it to be.
The atheist maintains that if I were to look the facts of evil in the eye honestly, that I would not be a theist. He not only thinks that evil is a reason why he is not a theist, he thinks that it is also a good reason why I should not be a theist. That's the dialectical fact that everyone keeps overlooking. Attempts by people like Weisberger to put the theist on the defensive on this issue are unsuccessful, as agnostic philosopher Graham Oppy shows with considerable effectiveness.
