Steve H,
What sneering, sarky etc would that be? My experience here is that it’s the atheists who, on balance, are more polite, patient and willing to explain than are the theists. The relentless straw manning of Vlad, the unremitting dishonesty of AB (who will never, ever address the problems of the logical errors he repeats over and over again) are just two examples. If you actually mean the teasing of, say, spoof book titles though then what on earth else is there to do in response to the theists refusal to engage with the arguments that undo them?
Oh, and you need to understand too that, absent any cogent supporting arguments, dismissiveness of religious beliefs is every bit as appropriate as dismissiveness of leprechaunology. If someone wants his faith beliefs to be given special respect then those beliefs have to earn it by force of reason - just repeating them doesn’t even get its trousers off for that purpose.
