Ow.
I am very sympathetic toward the OP, but you just can’t expect the same debate in the town square that you get in the seminary break room.
The thing is, it’s kind of important, in the answering of some questions, to be able to argue with the unspoken assumptions of the question. I actually started a Pit thread of my own on this issue, once, and I’d hate to see a board where one could direct the course and outcome of a discussion merely by wording the title carefully enough. That leads us away from pointless bickering, true, but also out of the realm of healthy discussion and toward (sometimes) equally pointless cheerleading, which is antithetical to fighting ignorance and to freedom of speech and information.
At the same time, there are some questions whose premises are, if not grounded in basic mathematics, at least well-known and widely accepted enough that the attacks on those premises are likely to be equally well-known and trodden into the argumentative ground. Metaphysics and religion are likely to fall into this category: it is known that certain facts not universally accepted form the basis of discussion, and it has been shown that a very few contrarians can bring what might be (in some less emotionally fraught arena) an energetic and entertaining discussion to a screeching, unenlightening, and done-before, deathly-dull halt.
Sometimes, in advancing understanding, it’s important to question, indeed, do one’s very best to demolish, the factual and theoretical ground underlying a question or assertion. The SDMB, taken as a whole, generally does a great job of that. Sometimes, I admit, understanding some hypothetical questions may require a suspension of disbelief, or at least a waiver of the more basic challenges. The SDMB is lousy at that. And it’s true that a man who has to re-invent the wheel every twenty minutes for some new critic will never build a DeLorean. But I’m not at all certain that the much-admired Mangetout’s analogy is all that appropriate either. If someone thought they had good reason to believe that pizza was poisonous, pernicious and seditious rather than toothsome, nutritious and delicious (and there are serious thinkers who feel about religion very like that), they might consider it their duty to spread their gospel as freely, as often, and in the same places as they see their ideological opponents spreading theirs.
I think the solution, when the SDMB community eventually arrives at it, will look something like this: (1) Threads will not be isolated from argument issuing from any point of view – it just invites cliquish logrolling and denies the fight against ignorance. (2) Moderators will take a harsher view toward repetitive posts – once an objection has been brought up and answered, and brought up and answered again, and then again, however well or however inadequately, it may be decided that the purpose of fighting ignorance has been fulfilled, interested bystanders have enough to develop their own opinion, and that further posts without added content are out of order, and the discussion may continue – or perhaps not, in some cases. (3) Posters will simply develop their own ways around this. I don’t like it, but pestiferous posters may find themselves simply ignored or given only cursory attention by other major participants in a thread, who will proceed as if the old, oft-debated, challenges simply aren’t there. The reason I don’t like this is that it’s just as attractive a tactic against reasonable argument, for those who don’t want to hear any dissent.
I don’t want the religion threads to fall into the same generic, by-the-numbers mud-hole every single time someone has a thoughtful and specific and sophisticated question to ask about their (or someone’s) faith. Nor do I want to see a special forum in which any sort of thread is permitted and no negative responses shall sully the OP’s worldview. Still less do I want religion threads, or any threads, to be immune from the kind of critical analysis exemplified by examining the assumptions behind the thread title.
Perhaps the SDMB is the kind of public forum, like some street corners, where passersby may distract and detract from what the originator feels is a productive discussion. Perhaps the originator would be happier in a more restrictive forum, or develop better tactics to contend with the loud noises interfering with what he feels is the productive part of the debate.
I am not in favor of the quaintly-named threadshitting; but if the opprobrium of the SDMB community can’t police this problem, I don’t think we can create a rule that will work to the benefit of both the individual posters and the board as a whole.
