This is exactly how I feel. As a child I was always taught to be kind and polite to everyone, and my first experience of shunning was at my very first meeting! I was ordered to shun a girl just two years older than me, just a teenager, who was disfellowshipped for having a baby. I had to watch her struggling with her tiny baby while all the sisters, including her own mother, ignored her. I wasn't even a JW at that stage, I was just someone's bible study. It still upsets me to this day, along with all the others I shunned over the years, just following orders. When me and hubby were fading and met a disfellowshipped brother while we were out one evening, it was wonderful to ignore the shunning rule and we spent two very happy hours chatting with him and catching up with news etc.
Shunning is completely wrong and I could never go back for that reason alone.
