It is very easy to presuppose—implicitly and subconsciously—that one is right, unknowingly using that assumption to justify later claims.

Oftentimes we therefore fall into a fallacy of ethical reasoning where we assume, because we have the right position, that we are licensed to do actions that someone else—coming from the morally wrong position—is not permitted to do. We can therefore arrive at a heuristic for ethical reasoning: If an action’s moral right- or wrong-ness is determined solely by whether its doer comes from the ‘right’ or the ‘wrong’ position, then the justification for the rightness of an action is probably faulty.
