It seems that since Ray eventually DA'd himself, his uncle who had the power in the publishing and real-estate firm (WTS) decreed that nobody could talk to DA'd people any longer.
Actually, Raymond Franz never DAd himself. He was disfellowshipped for associating with Peter Gregerson who had DAd himself. The unreasonableness of the situation is obvious when considering the fact that Gregerson was Franz's employer and landlord at that time. Franz was caught eating with Gregerson in a restaurant, and was disfellowhipped for this.
As far as the Scripture: "not of our sort" that the WTS cites as a proof text; a closer examination of the text will show how this Scripture has been grossly misaplied by the Watchtower theocrats. At 1 John 2:19, John is speaking of those "not of our sorts", but in the context, he is speaking about "antichrists". This is speaking of those who have rebelled against God and Christ (abandoned the Christian faith). Nowhere does the text indicate that it is speaking of persons who cannot conscientiously follow the dictates of certain men (or an organization). But, in Watchtowersm, God and the Organization in Brooklyn are one and the same. Hence, this kind of Scripture twisting is par for the course.
