He does not wish to publish the verse in full; The idea they have is that by quoting verse number only it prompts the grateful flock seated at the feat of these fonts of wisdom to go off and read the relevant text instead.

The reality of course is very different. Those self-declaring as atheists have, as Vulcan has already pointed out, already "seen the light", and recognise religion for what it is; an outmoded belief model from more unenlightened times,created by man mostly in some kind of attempt to explain the world around them but unfortunately with a tendency to continually interfere in societies changing cultural values, mostly in a regressive manner. The JWs are simply a more extreme form of christianity, a sub-sect, or cult,if you will.
