If there is any good that comes of the shunning policy is that the Society will continue to receive bad press. That bad press is now everywhere.
Anyone studying with Jehovah's Witnesses with an inkling of curiosity and a smart phone will learn that this policy is part and parcel of this organisation.
Many of us who came into this religion before the days of the internet had no idea such a cruel policy existed. I certainly didn't.
Keep up the good work Watchtower leadership. That's the kind of publicity YOU really need going forward as an organisation!!
