Good point. They already say what you have predicted. I hear it all the time.
I have found that JWISM isn't about doctrine. It's about something more. I thinks it's fear of life and of one's self. It's power stems from the false sense of security found within the group. That's why they can change beliefs from day to day. Perhaps this is why it takes something profound to wake a JW, usually some injustice and then TTATT follows.
I imagine dubs as a tiny group of primitive homonids, clinging to one another on an isolated island. Sometimes a predator snatches one from the fringe. Sometimes a brave soul swims to the next island. Meanwhile the great cycle of life continues around the Earth. Most inhabitants are totally unaware of the tiny fearful dubs on Dub Island, but the dubs believe their island to be the center of the Universe.
