Remember that JW's are told to use the literature as service material - not their own thoughts. They are told to stick to the script and have the Watchtower do the talking. This 'rule' goes back to the beginning of the organization - recall the phonograph records? Now it's the cart method.
Unlike decades ago, Witnesses don't read their Bible - they parrot the ideas of Watchtower literature and videos - and attempt to use a couple of cherry picked scriptures (with no understanding of it's context).
