Objective morality as a proper basic belief

[Little Henry]

Henry, I view all morality as subjective, even if it comes from a god (in which case it's the god's subjective values underlying a code of morality).

Under Christianity, morality is not subjective because God's commands do not come from his opinion, preference or taste. It comes from his nature. His commands flow on from that nature.

There is a natural tendency for certain values to become prominent in successful societies.  It's difficult to  feel safe in a culture where killing is permissible, so one would expect to see a lot of people defecting to safer tribes where the moral code prohibits killing and members of the tribe protect their neighbours from harm.

This all comes down to preferences/desires. This does not make it right. Is it a fact that societies ought to be successful? Under naturalism, no. 

IMO, moral codes are beginning to move beyond basic needs like physical safety and are becoming more supportive of individual differences (on the condition that those differences do not cause direct harm to someone else, which would be a violation of the need for physical safety).  In that regard, one could possibly create a hierarchy of morals analogous to Maslow's Hierarchy of Needs.

Again, this does not make it objective.
