? I don't understand your question. Morality is unitary - that is a conceptual claim. It has nothing to do with what morality instructs us to do and be.
Even if (as seems conceptually incoherent) there are lots of moralities, they could each tell everyone to do the same thing. And if there is one morality it could instruct everyone to behave differently. The unity of morality and the content and scope of its instructions are totally different matters.
