The JW cult is going no where. It will remain, more than likely, smaller in size. I agree with what someone else posted earlier, their doctrines will be exposed more on the internet and you will see no growth. Any hope of survival will on the backs of the born ins but I am sure some will decide to jump ship there too.
As frustrating as this is, I always remind myself that they will NEVER receive another cent or 1 second of my time ever again.
