I totally disagree with the shunning practise and even as a JW I did not think it was a godly practise and refrained from it.
My JW gran has been admitted into frail care because her legs and feet are going numb. I wanted to go visit her to offer help, be it financial, emotional, or even physical, but was told not to go as she still doesn't want anything to do with me.....Your loss gran.
