I think the STUPIDEST rule regarding disfellowshipped ones has to be regarding if a relative lives in the home of a JW or not. Where in the Bible does it say that you can talk and not shun a df'd person if they live in your home but if they don't live there, you have to avoid them and treat them as dead?
The Organization decides if a df'd person could live within the home. If an elder allowed his child to come back home while in a df'd state, he'd be considered not exemplary and would get removed BUT if the same child was already living there, he might not be forced to kick his child out of the home.
If the df'd relative was healthy then they should not live in the "faithful" Witness' home but if the same person was ill, they could possibly stay in that home.
Does any of this make any sense to you?
