After reading comments on this site for a while and looking at what happens to other religions I feel the Watchtower Society has a long future in front of it. This is bad news all round, sad for us waiting for our families and sad for Witnesses waiting for paradise.
The reason I say this is that any organisation with 6 million members, billions in assets and little to spend their money on would find it very hard to go out of existence. When things start going bad the money can be used to find the best minds to come up with better marketing plans, more sensible doctrines, up to date ways of advertising and so forth.
Look at the example of Scientologists. They receive ongoing bad publicity and are growing quicker than ever at the moment. They have not stopped from using the law to further their cause, as the WTS has done over its history.
Dramatic doctrinal changes are not going to kill off the Watchtower Society either. It hasn't in the past and won't now. 1914, 607, the trinity or any other doctrine can be changed without make very much difference.
In the 1930's the Seven Day Adventists changed from being anti trinitarian to trinitarian and are still around and as strong as the Watchtower society. In the 1990s the Worldwide Church of God likewise went from being anti Trinitarian to Trinitarian. They were not very subtle and made changes to numerous doctrine all at the same time and though numbers dropped dramatically they are still around. Even the WTS went from worshipping Jesus to not worshipping him in the 1950's without any drastic affect.
We can not hope to destroy the religion, so a more realistic goal is to change it for the better, assist in changing it from a cult to a bearable religion. Using free speach on this site along with the courts we can force an overturn of many of the evils that it propogates. The two that I find most abhorrent are disfellowshipping and the blood doctrine. A lot has been done over the last decade to remove the blood doctrine and it is no where near as deadly as it used to be.
I do think that now is the time to be making more of a mark against the policy of shunning. The UN, the courts, the governments and the press should all continually be approached around the globe. With the fear people have of terrorism and extreme fundamentalism I think this is as important a decade as ever to make an impression on the world around us. Eventually the WTS will see the need to change. If not they will be forced to ease up on this unchristian and inhumane policy.
