My observation is that while religious
people are kind and charitable, religious
societies tend to be the opposite. An example is that the US is full of charitable organizations, yet in the aggregate, we are relatively uncharitable as a nation, especially towards the poor and weak. And how religious organizations actually spend their money overseas is anybody's guess, when a little bit of money can buy a lot of political power in a poor country.
From my reading of the gospel stories, this doesn't shock me. The religious doctrines have a lot to say about individual behavior, whether you agree with them or not, but nothing to say about how societies and governments treat people. In fact, my impression is that the gospels consider societies and governments to be irredeemable, and offer the "good news" of basically saving the good individuals and incinerating everything else, soon.
With this said, I'm hesitant to make a strong argument of this, because I have a rule that I don't try to interpret anybody else's religious doctrines or holy books. I hope that someone's religion motivates them to build a better society, but I can't prove that such a thing accurately reflects their doctrines.
