VANDERHOVEN & SLIMBOYFAT:
If the religion is discouraging DF’d people from communicating with each other it is because it is afraid people ‘will compare notes’ about their experience in the religion (“Suzie Q and Joe Blow had the same thing happen to them..”)
The last thing they want is for people to talk about issues and injustices they faced in the religion and elders who did what, etc. They want to compartmentalize information. This is why they want to isolate each ex-JW so that they have nobody to talk to and will not hear about other bad things that happen there!
