I know we cannot answer this, how many are physically in, mentally out (PIMO), but I heard an amazing piece of News the other day.
An ex-P.O and ex-Elder, a long time Regular Pioneer, and when I knew him a stalwart believer, went for a drink with another JW who has actually left, but is not DF or anything.
In the course of conversation he came out with this Bombshell "Well, I am actually an Atheist now, I just go along to keep my wife happy".
I also heard of a number of youngsters that I know personally who are simply living their life as they want, whilst making sure they don't get DF'd for family and social reasons.
If as it seems the PIMO's are a huge number, could there be a huge " Awakening" where they all realize they are in a huge group, and they all say " Eff it, lets call it a day on all the JW s**t ". ?
Wishful thinking, but.....just possible ?
