I think they know exactly what they are saying. They are saying the faithful get disfellowshipped and they know it because that is what they are doing. Just look what happened to Ray Franz, let alone ones like myself and plenty of others.
They are also saying if you are a coward like the parents, shut up or else you get'll get chucked out. The Word of God is a double edged sword getting to the truth. The Watchtower is a double-barrel economic, psycho-sociological mind-trap threatening you to shut up and go along with a pack of lies. Abandon your intellect and integrity or else.
