ST. ANN- I see the point you are making - but I think it's kind of a generalization to state that ALL Ex-JW's don't communicate well with others . I feel it depends on , not only being raised in the witnesses, but a person may have learned good communication skills from parents in their home environment being raised - even as a witness - like myself. My witness mom is a great conversationalist and knows how to communicate well with others. I've been told I got some of that skill from her, and I agree.
So it not only could be a " witness thing " that makes it hard for people to communicate ; but it could be a " environmental thing " in that young people were not taught good communication skills from their parents - so they carry what they have learned , or not learned communcation wise into adulthood , thus resulting in problems for them. Just my take. So it could be how they were raised, not just the witness cult
