On average, the right gives more to charity than the left, and in America this is by quite a significant amount.

Isn't quite alot of this money directed in political ways ? or is that discounted...

I would hardly call giving Israel money charity (or at least no more than giving Hamas money is charity)

Same goes for the opposing camps in the abortion war...

Is this money adjusted for different wealth between countries ? (obviously if you have more you can give more)

Amount of millionaires and billionaires ? (they can give away half thier money possibly without having an effect on thier lifestyle, the average man cannot)

Population adjusted also ?

Also im sure alot of religious donations go towards keeping churches going and recruiting new members...

Theres alot of charity with selfish motivation behind in, with America's paticularly hostile debates on some issues its high levels of religious belief and religious fervour (the televangelicals spring to mind) and its closeness to Israel could add up to a decent share of its contributions..
