“Objective” morality is a misnomer for religious morality, it's just subjective morality ascribed to some mythical authority figure (and, even if that figure actually exists, for most religions, given the diversity of different moral systems ascribed to the divine judge, those are clearly misascriptions, largely reflecting the personal subjective morality of the people doing the ascribing.)

I'm personally religious, but the myth of objectivity is a very, very dangerous thing; in masks the ways that man creates God in his own image.
