The group of people when on to a common census over the morality of a particular thing, is said to be in moral union.
Step-by-step explanation:
The concept of moral union is in order of denial of comparison of any or two sides to be in conflict morally. The action or the tactics of the action must not be given side morally.
The term has been in use since cold war ages and has been use for the political terminological implied actions. This on broader aspect, correlate to moral relativism.
