What would the JWs say if everybody in the World shunned them they would claim persecution right well that's just what they are doing to all their ex members who no longer agree with their nonsense . Shunning is a way of keeping the rank and file in line and woe betide any member thinking of becoming a whistle blower it would cause the Governing Body to throw their toys right out of their collective prams.
Tell them straight that they are going to grow old and die just like everybody else on planet Earth. I was right in 1965 they were wrong when I told the so called elders the same thing and sure enough most of them have gone now or are on the way out . If anyone wants to shun you tell them to grow up and get a life and do something useful.
