I've noted that one of our ex-members believes that the vast majority of posters to this site are, in his opinion, worthy of the label of being "dysfunctional".
For what it's worth, I believe that some persons, especially those who have exited the witnesses fairly recently, may well be a little naive and probably somewhat immature also. From my own observations I have seen how maturation virtually ceases when anyone becomes overly committed to a belief system. Once someone leaves that belief system, then their maturation continues afresh and goes into over-drive as the person strives to "catch up" and eventually feel comfortable in relatively normal society.
So no, I don't think that many of us are dysfunctional at all. Maybe a bit immature at times, but definitely not dysfunctional.
Maybe you feel differently?
