Great logical points Elsewhere!
Might I add that if you have letters from family they can be used as evidence.
I have letters from family telling us that 'if we come back' they can have association and that kind of thing. This clearly indicates that unless you belong to the group that you will be shunned. Further the assemblies notes such as the ones that were put up on this site, telling members that they will not have association with disfellowshipped people, would be good.
I would like someone to get on tape, an Elder telling a JW that they will be disfellowshipped for being with another disfellowshipped person. That sort of thing - sammieswife.
