The only way they're going to change the shunning policy is if ex-Witnesses were successful in sueing the WTS in court. So far that hasn't happened. Barbara Anderson had a very strong case but the U.S. court system simply ignored the horrific results and injustice for the individual and reiterated about the "Rights" of the religion itself to enforce it's own rules. The same thing happens here in Canada.
I find it ironic that a couple of years ago, the Islamic Sharai Law was struck down here in Ontario, no doubt because it was seen as backwards, barbaric and dangerous, yet the government doesn't see that the extreme form of shunning practiced by the Witnesses is no damn different.
Neither the Governing Body or their henchmen lawyers give a damn about doing what's right. They don't care how many families are destroyed or how many people commit suicide over the shunning policy. The only thing they care about is dollars and cents. Until someone successfully sues them in court, their policy on shunning family members is not likely to change any time soon.
