I've invited Witnesses to treat me and all my friends and family with respect or stay away. I've had them try to talk to one family member while snubbing another and those Witnesses who were stupid enough to think that'd work were invited to leave.
I allowed my Witness parents access to my sons. That was a huge mistake. My dad studied Witness material with my son and my son joined the Witnesses. Then both my dad and my son shunned me. My second oldest son shuns me to this day. Now he's disabled and could use my help but he won't accept any contact from me.
Allowing Witnesses access to my family has had an extremely bad outcome. I won't make that mistake again. I'd advise anyone who has Witness connections, and a family that they care about, not to allow the Witnesses ANY access to the family at all, especially the children. Why risk it all?
The only people who can hurt me or my family are people I trust. I won't give people I don't trust access to me or my family. I let loyalty to parents, naive trust, and honorable expectations get in the way of pragmatic parenting. My job was to protect my family from harm and I failed because the harm came from my father, whom I trusted.
Now my father's dead but the harm he did is in it's second decade. If I had minor children, I wouldn't let a believing Witness within 100 miles of my children.
