@Naomi - I think it has something to do with the rarified air perched high as they are on their mountain of religious holier-than-thou -ness that shuts down the politeness and manners gene - instead, all we get is finger waving, smug moralising and unshakeable certitude in the rightness of what they do.
As to prayer - Christians have long claimed that prayer is a means of contacting God, and that prayers can be answered. Christians have long claimed that prayer can heal - witness several high profile, preventable deaths of mostly children who, but for the blind faith of their parents and community, could have been healed and lived a long, fruitful life.
So, given these claims, and the certainty and moral rightness with which they are expressed, it seems entirely appopriate to see if, in fact, such intercessory prayer works - and guess what? No evidence to show that they do - what a surprise!.
If you want to pray in private, or as an act of collective worship with like minded individuals, then thats ok - but what isnt ok is to go around claiming with certitude that prayer works, or that it can heal the sick. As I think it was Ratter said earlier, God must really hate amputees - Come to think of it, that might be the one piece of evidence that would give me pause for thought - if, through prayer, an amputee miraculously grew back a full limb...........
