Interesting. When people claim that religion contributes to things like radicalism, homophobia, terrorism, etc., you tend to dismiss their claims by suggesting that people have those tendencies anyway, and if they didn't blow things up in the name of religion they would blow things up for other reasons. It would follow then that perhaps religion is not the cause of humanitarianism, but that those people would be humanitarians whether religion existed or not.
To repeat Phi's request, do you have any evidence that it is "religion" that is making the contribution, and that without it, those humanitarian acts would not have occurred?
