According to the GB's teachings, one in particular certainly does - shunning!
FACT: According to the zealots in the Org, the Bible categorically demands that those who leave/disagree with the GB must be shunned - no compromise - and failure to comply will result in very strong discipline for the offender.
Most Witnesses haven't woken up to the truth that God's "law" on shunning is really flexible, depending on your postcode/zip code!!
Example:
Witness parents who live in Zone A of their town, have a baptized 17 year old son. Son subsequently gets D/F'd. Family life carries on as normal - vacations, conversations, meals together, caring for all his material needs, etc. The only changes are that the parents don't discuss "spiritual matters" with him anymore, and other Witnesses no longer visit his family's home!
Game changer; some time later, son decides to move out and rent his own flat in Zone B of the same town - bad move!!! Now the parents are compelled to disown their son, and cut him off from their home - simply because he now no longer shares the same address!!!
JW's really need to examine the perverted doctrines which are presented as "God's loving direction".
