As for Ben’s ultimate motives, I actually think that Ben himself, like countless others who behave similarly in these forums and elsewhere, is less than secure in what he believes in, perhaps subconsciously, so that he doesn’t realize it. All this talk that his own beliefs are absolutely proven beyond the shadow of a doubt (when, as I have argued and demonstrated, no one, including Atheists and even Agnostics, can hold their stance without having some degree of faith) suggests that he needs to believe this in order to have some sense of emotional or intellectual security. If he admits so much as the fact that Christianity is intellectually feasible (which no unbiased person would deny is at least conceivably true), it will be too big a blow to his own beliefs due to his insecurity; since Christianity contradicts his view of Judaism, and he seems deeply insecure, he therefore cannot accept it even as an intellectual possibility, nor can he simply buffer his own beliefs with faith in light of that possibility–as he has admitted he cannot–and so feels the need to endeavor on the hopeless quest of totally “disproving” Christianity, something in which no one can succeed but in which Ben, similarly to Atheists and Agnostics who also deny the place of faith much to their own peril, must falsely convince himself that he has already succeeded. He is fighting for his own mental certainty, for his very confidence in his beliefs, and so he will likely never yield to the fact that his “proofs” are really nothing more than (in his case highly subjective) evidences, if even that. This is what happens when anyone, religious or atheist/agnostic alike, forgets that having faith is not a weakness, but is rather a human necessity.
