Sorry if I am doubling up on the thoughts of others, I only had time to quickly skim through the posts.
It has always bothered me how witness parents take the high road in the cases of their disfellowshipped children.
They are YOUR children, maybe something YOU did as parents contributed to their struggles and consequent disfellowshipping. They have YOUR DNA, your strengths and weaknesses. As a parent you have no right to simply wash your hands of your children's behaviour and walk away unless you have absolutely done everything in your power to help your children. They did not ask to be witnesses, that was YOUR choice.
On the other hand, you have 'worldly' parents whose children are dealing with addictions, mental illnesses etc etc, yet these parents never walk away from their children. Even when it takes years, in some cases, for their children to recover.
