I don't want to put words on MS's post, but we've had similar discussions in the past and I think our differences lie in a disagreement about the ultimate source of religion. MS is a Christian theist who I think believes religion is implanted in us by God and we naturally are theists. So, if people are not theists, they have perverted this natural religion and created a substitute religion because for one reason or another, the natural religion is unacceptable. (MS--correct me if I misunderstand) I think this view has a long history in Christianity and it's correlated with the idea of original sin as a turn towards humanism.
I disagree with this accounting of religion. I think it's historically false because monotheism is a pretty late development in human culture so it can't be 'natural'. I also thinks it sets up materialistic naturalistic humanism as a 'false religion' or a deviant substitute for true montheism. I also disagree with it because it is a supernatural account of religion. I think natural accounts of religion are all we need.
Again, perhaps I misunderstand MS. But I do think our differences are not just semantic but substantial.
