Those are all matters of moral psychology
, which have nothing to do with moral ontology
. The question is what are moral properties themselves like, not what our perceptions of them are like. But I would ask a similar question: have the staff at STR read any of the works of Michael Huemer, Shafer-Landou, Richard Boyd or other atheist moral realists? I don't see how theistic theories of moral ontology are better than atheistic ones. In fact, theistic theories just seem inherently worse on account of their being subjectivist, in that they seek to ground morality in the attitudes and evaluations of a person (God). I would argue that the objectivity of morality is strongly incompatible with theistic metaethics and even theism itself (since as William Lane Craig argues it's greater to be the standard of morality, rather than just another good thing).
