At 37 years of age, I'm much to young for feeling this damn old, so apologies for sounding less than idealistic, but.....
We need people who will be honest and true to themselves. Having offered JWs the entire decade of my 20's while they tried to suck out my soul, I have come to appreciate how little of a desire these days i have to change the world.
Which was sad at first. I used to sell 'Living Forever', and all sorts of other large ideas. It feels great when you drink the kook aid and believe that you're doing something great and grand. It's also a letdown when you realize that you not only bought the lie, you tried to sell it!
So I hope you won't mind when I try to be realistic and point out that movements that try to bring down JWs are essentially a waste of time. Former JWs alone working to bring them down won't work.
However, what will bring them down is when you live your life, (something that does bother the leadership) and try to make a difference. Randy Watters, Barb Anderson and others who have been pretty deep in and who are just honest and put out there what is really going on make a huge difference, and they have personally helped me greatly Lawsuits over criminal activity will also help.
Basically, as with all corrupt groups, JWs will destroy themselves with their inner rot and the hubris of their leaders. I, along with others, have tried to expose with our stories what we know and saw. Speaking personally, my goal was never to "bring down" JWs, but to be a resource for anyone honest enough to consider what the facts are.
I think if you really feel the need to change the world, you're going to have to go down that road. But you don't need to change the world to make a difference. By being honest, you can save a few people out there worth saving, starting with yourself.
