I remember in the 70's the WT corporation used to furnish us with a card declaring us a minister representative of this corporation, and then they suspended this card use and would no longer endorse it's members as representatives I think it was announced in a kingdom ministry somewhere back in the 70's.
The Watch Tower Inc. has made its members believe it is their exclusive duty to preach their propaganda and therefore they can not divorce themselves from this door to door activity. They even brag about how they alone as a corporation and its members are faithfully carrying out a divine mandate with life and death consequences for to both themselves and the public. I think a good lawyer would know how to present a case against them that would spell a corporations nightmare in legal problems.
These guys on the Governing Body are such a bunch of in denial delusional dopes, with a touch of hardening of the arteries. So I eventually see them driving this corporation into the ground both legally and in public opinion universally thru out the world.
