FOOLEDNOMORE:
You said it right. It’s a schoolyard mentality. And you don’t have to be disfellowshipped to be shunned. Just be slightly unpopular for whatever reason Or gossiped about by the ‘right’ people and you get the treatment you got.
I wonder if any of your shunners were among those pestering your family for money? They got colossal nerve if they were! As a side point, Witnesses who shun their children have No business looking them up for a$$istance when they are old. Likewise, anybody who shunned responsible working people.
Aren’t you glad you’re out? I’m so glad I’ll never have to deal with these people and their games again.
