Very frustrating for you schnell. She really wasn't telling you to kill yourself though I'm sure. Families still in drive us mad I know, mine haven't budged for 27 years.
If she's willing to listen I think a good approach might be saying it's all very well the GB being imperfect and changing things but what about the people that disagree before they change it again. Can it be right to disfellowship people for disagreeing, having a transplant or using IVF to have a child and then the teaching is changed? How come they don't get an apology from the elders and immediately reinstated?
