Objective morality as a proper basic belief

[Whateverist]

According to you, a Theist is someone who is delusional because according to you, God does not exist and the Theist is imagining God exists  and is acting according to it.

Sure, no point in wasting ink trying to communicate why -I- think you're delusional, because it doesn't matter to our discussion.  If ghosts aren't telling you what's right and wrong, you still think that some act x is wrong.  It doesn't actually matter whether or not ghosts are telling you that.  

Similarly, if it's.."just like, a subjectivists opinion..man," that some act is wrong....it's still their opinion that some x is wrong.  You don't really have to agree with them (and vv) as to why it's wrong, but you both agree that it is.  This is how objective and subjective moral theorists can come to moral agreement.  It;s how believers and non-believers can come to moral agreement.  There's alot of moral overlap between all four groups, and between the moral statements of all four groups.

@Little Henry - So here is how morality can be objective without any gods. It starts out as subjective. But then you take note of what morals people just do happen to have in common - and by far nearly everyone shares almost all morality in common. So then you look through all the morals people have in common and you start noticing common themes. From those you distill a hierarchy of morality - things like non-harm, mutual support, reciprocity, the usual suspects. That hierarchy of morals is objectively the morality of our species, the distillate of those 'shoulds' which have best served us and therefore been selected for through natural selection and culture.

If this seems hard it is probably because you subscribe to belief in radical free will. No one has dispositions which largely determine actions; according to that point of view all actions are freely chosen. This leads those who share this POV to imagine that either behavior must be governed by OM facts or else behavior would simply be random - which clearly it is not. But our actions are not chosen on a purely rational basis. I'm sure to a highly intelligent alien our actions would seem as predictable as those of a pet dog. We just don't see it from within our human framework. It is very hard to distinguish which actions reflect a rational decision and which show the sway of our dispositional heritage. That doesn't mean we don't have one. Those are the facts.
