You are dealing with a family "culture". It is like a cult. There are secrets and taboos (such as talking about the secrets) that are "imprinted" onto the family from birth. If you dare to confront the "secrets" you are hated and cast out. The "brain", "nucleus" of the family will devalue and discard you. If they have nothing bad to say about you they will "make up perverted lies". The N who made up all the lies will believe them herself. Their whole existance is based on these lies so if challenged you are challenging their "existance. This is twisted and crazy.This is all accepted as the truth in the family cult. It is disfunctional, crazymaking and evil. This is life in a family ruled by a N. If you try to tell people outside the family about this crazy making they will think you are unstable. That is why this site is so valuable.
Never correct a scoffer or they will hate you.
