3. And what effect has the increase in the incidence of the "fade" had on local congregations of Jehovah's Witnesses?
Not so much the increase, but the quality of the fade is what's important. In the old, pre-internet days, a fader was almost certain to come back into the fold at some point. The old "Where else can I go?" philosophy. That's all changing now, thanks to the internet. There ARE other places to go now. Not only do Ex-JW meet-ups and internet groups offer therapeutic encouragement but they also give advice on social alternatives so that these lost souls who have been stifled, sheltered JWs all their lives can now open up to the big wonderful world out there.
