RWC: It's a control thing - if they are different from the world, then it almost seems to 'vindicate' the Governing Body's 'research'. This is then used to prove the case to outsiders, ie. 'worldly' people.

That is why most younger Dubs today are encouraged not to read very old Watchtowers, and not to read any of the really old books that the WTBTS published. Are you familiar with the farcical practice of "New Light" which the WTBTS seems to introduce to cover their asses every now and then? I suggest you read the archived threads on this board a bit, and do a search for the WTBTS on Google. Your questions will then be answered.
