I had in KH extremely zealous pioneer who would cover extremely difficult territories. Her husband was just regular dub, but she never missed any meeting. To everyone in the KH she was nice, especially to children. She had a son who was married and had a kid. Later he made another woman pregnant and was DF's for it. She shun him and his two children to the rest of her life. She would never talk and when the kids were calling her granny across the street, she pretended she does not hear/see them. She was very thorough in shunning her son and his two children until she died. She never reconciled. My aunt shunned her son once he DA with JWs. My ex-elder has a gay son, who they do not talk and he is forbidden to talk to them..
JW is not so loving religion. But people accept the membership and they pay it with broken family ties. After so many years of shunning, many people will move on and the damage is not repaired.
