Religious people often see morality as one domain that they can really claim as their own.
Yes, in fact the most common defence one hears for religious faith is not that there’s so much evidence that God exists, but that religion offers the only basis for a universal morality. Moderates and fundamentalists seem to agree on this point. Of course, it makes no sense as a defence of faith because even if it were true, it wouldn’t suggest that God exists. But there is the additional problem that religion is a terrible source of moral guidance in the 21st century.
I happen to think that the scientific study of morality is the lever that, if pulled hard enough, will completely dislodge religion from the firmament of our concerns
