You are making some great points!! This internal inconsistency in their philosophy reveals the bankrupt and actually psychotic basis of moral relativism. The foundation, or center, of moral relativism is a constantly shifting phantasmagoria of whatever feels good to someone or other at any given time. And anything with has a scent of eternity, or moral absolutes, terrifies and enrages them. That's why on the one hand, they hate traditional marriage and the religious concept of the husband as the head of the household, on in this situation, they have no problem giving the HINO who has a girlfriend on the side life and death control over his "wife".
It is more than psychotic, it is the face of evil.
You've got that right.
