Regardless if that video is true or fabrication for that specific person, that scenero does happen and active JW's are shunning elderly parents and visa versa with grandchildren. It's sad but the situation does happen.
This is why the governments all over should step in. That's why Russia is giving the JW's a hard time. They break up families, either you're in or we're severing relationship ties.
This brings up a whole different topic. It reminds me of a video of a skit at a convention where the parents were interviewed and how they proudly boasted how they would give their life for their son but if he were to ever leave Jehovah they wouldn't be there for him. The shunning doctrine does not cause people to return to Jehovah because they truly love Him. Disfellowshipped people 'return to Jehovah' because many want their family and friends back and that's the sacrifice they are willing to make. It has NOTHING to do with loving God. Shunning is a control mechanism.
Governments should heavily inspect (not just JW's) religion and any religion that does not offer some sort of charity within the community (even something as simple as volunteering for a soup kitchen) then their tax exempt status should be stripped. What charity does JW's do? They only do for themselves and only for the 'elite'. Sure in a disaster they might assist those that are nearby, but that's only to save face. They don't go OUT into the community for the purpose of assisting all.
