People who are unhappy sometimes get consolation from seeing to it that others are unhappy too. Misery loves company.
You have to have that "get off my lawn!" posture . i agree w/ the Amway reference. How do you stop these sort? Sometimes, you have to hurt their feelings to get through to them. You've done that already, and it worked. If they take it to the next step, just keep doing the same thing. ... let them know (in your own way) how offensive the intrusion is to you to the point of making you want to quit the religion entirely. And that's honest too... "You offend me". They don't want to stumble anybody, so use that against them. I finally told one elder: "I told Jehovah to just let me die" ...he asked: "you mean at Armageddon?" I said: "I don't care when." He got up immediately and walked out of my house (i think he got afraid i might do something to him). Never had any trouble after that. He knew not to mess with me.
