I have not experienced "Shunning" yet, I have observed Jehovah's Witnesses shunning members who are not disfellowshiped, I think this has to do with selfishness inheritant in this religion. Christianity is a religion of giving, Jesus wanted his members to share their goods with people who could not return the favor. He promised his Father in Heaven would repay generous hearts who looked out for father-less boys and widows.
Fine and dandy, but in the real world, quid-pro-qou matters, returning meal for meal, gift for gift and party for party does maintain your social status in the congregation. There is deep bitterness that arises when people feel neglected, "I invited you over for dinner twice, and you have never had me once!"
How close were you to your family that are shunning you because of your decession to stand back, you got disfellowshiped, left the organization on your terms or faded?
Honestly evaluating the time spent, how real was your relationship with these people? You know how quick their view of you can change, do you even care if you ever see these people again? Do some family and friends cheat, and talk to you? I find the most evil ones enjoy the shunning the most, I could see them walk past the beaten up Jew, who the disfellowshiped Samaritian took under his care and tent!
