Ought implies that the world is one way, but should be another.
So within the Ought is an implication for what already is. It’s unsaid but necessarily implied.
You have to get an Ought from an Is. Otherwise there could be no “should be another way”.
Furthermore Ought implies an improvement on what Is, on behalf of the person proposing the Ought. This is where moral disagreements occur. Because, almost always, the Ought is biased to the-self. So person A says it Ought to be this way, person B says another way, and person C says another way as well. Ought is self-serving. Sometimes, people will agree to some general Ought, because it is helpful to their own group, but is detrimental to other groups. This is political-census and “the majority”, sociology. Ultimately, everything must start from what Is, and if the interpretation is accurate (superior) or inaccurate (inferior), then the Ought can proceed to what is morally good (better) for one person or a group, or morally evil (worse) for one person or a group.
Now the hypothesis can be made that people Ought to be “on the same page” (Bible?) concerning the origin of morality, but that is rarely the case. Some people start with science and ‘Evolution’ of sociological interaction within species (kin-selection), while the masses and most of humanity start with religious indoctrination and God’s Word. Why do most people start with God’s Word? Because it’s easier to proceed through life having somebody else (Priest?) do your thinking, believing, faith, reasoning, and moral guidance for you. It’s easier to outsource then it is to Do-It-Yourself.
Because moral-belief has been outsourced for so long (to Theologians, Moral Authorities, Priestly Class, etc), the “Reality” of moral origins don’t really matter. It doesn’t really matter to the person who believes in God’s Divine Creation, and Damnation to Hell, whether his/her religious belief is “real” (realistic) or not. Instead, people are pragmatic, especially women. They will do, say, and believe as the Priest/God commands of them, because they desire the practical benefits of it. Churches instill a sense of community, reinforcement of moral order, marital laws, relationships, the ‘Joy’ of fanaticism, etc. People mostly want the Benefits. They want the cake and fruit-punch. The mumbo-jumbo of moral dilemmas is left up to “their betters”, meaning priests or anti-priests (philosophers).
