Do Christians really contribut to society more than atheists

[robvalue]

I always find the charity aspect a dodge. I'd rather directly support a charity than have just some of my money end up there, while the rest goes to god's overheads. It's like when zoos do a bit of (legally required) conservation work to make out that they're working in the interest of animals rather than exploiting them.

I don't judge anyone in advance by their religion, or lack of. They might do great things for society, or they might be a shit. I don't think general statements are worth much.
