To stop the shunning, is very critical to JWdom. Shunning keeps the cult in control, strong.
Shedding shunning, even gradually, would allow for the 'personal conscience' to develop. Then, one's start developing their own guidelines. They will get more comfortable to 'think,' to define what is really bad or not. Like whether they personally will socialize with their relative or friends that formerly would have been df'd. Then others will start thinking their conscience is clear to celebrate a birthday of a 1 yr old or not or an 80 year old family member. Then, Thanksgiving, which not truly of pagan origins, etc. Higher educaion will become less threatening. Many members would gradually integrate into the real world. They will begin to trust themselves that they won't be getting evil (as the WT threatens).
