So you can confirm that disfellowshipping actually occurs, Truthabounds? I have certainly seen several anecdotal stories about people being shunned, and it appears to a practice sufficiently well known that it has a place in Wiki.
I understand the practice can be very distressing for those who have family members still within the church - some of those shunned have been sufficiently exercised by the process to describe it as a form of implicit social blackmail/coercion.

Again, referring to Wiki, Shunning is decided by a judicial panel -presumably men - and is applied where there is evidence of a serious sin - and when you look at the list - sex out of wedlock, homosexuality, adultery, apostasy, reviling - demonstrates the obsession and continual hang-ups most of these patriarchal cults have with human sexuality. It would seem that their god is still a jealous god, since apostasy is a serious sin, and whatever you say, dont curse.
Does shunning have an expiration date?
It is a pity about the black list though - any additional protections from doorstep evangelists would be welcomed. We all have god to thank that such cults are so irrelevant in modern day society....
