It seems inconsistent to be denying moral realism and then making claims about what sort of language we should be using.
The thesis doesn’t claim “we should do X” but rather “X is an effective way to to reduce misunderstanding and conflict and change generally prevailing social conditions.” The inconsistency only arises if Greene bases in moral realism the assertion that reducing misunderstanding and conflict is desirable and the prevailing social conditions ought to be changed.
