can anyone verify the truth or otherwise, of a US survey finding that believers gave more to charitable causes[and not always specifically christian ones]?

Let's just suppose someone verifies that for you. What would it prove? What if I told you that there are many Christians in positions of political power who serially act to ensure that there will always be huge numbers of people who need these charitable causes? Two of the most explicitly prominent Christians in recent political life, Blair and Bush, plunged tens of millions in Iraq into poverty and misery and in need of charity, and had quite a bit to do with allowing Gaza to happen to boot. Do you think I'm going to contemplate using that as an argument against Christianity? No, I'm not. But I might use it as an argument to expose hypocrisy. Be careful what you fish for, Pete.   

steve-it still interests me that one so anti religion, accepts[ the fruit of relgion]religious music and architecture-though glad you do,as its the nearest you get to accepting christianity.

So, you want me to believe that great art and music can actually be the "fruit of religion." You'd better be careful there, otherwise I might just start listing some of the less desirable "fruits of religion," which are many and virulent, but which I tend to avoid rattling on about (I can't bear it when people rant on about the evils done "in the name of religion", because usually they were done for other reasons unnamed), and I prefer to be honest about that than to jump on to it opportunistically, as you appear to be doing here. There are many reasons why some people made religious sculptures or set religious texts to music, but direct inspiration from God was not one of them. Witness the rather obstinate and inconvenient fact that the self-same were just as adept at creating great works in the realms of the profane as well as the sacred. As ever, your reasoning in these matters seems woefully incomplete.
