There’s a darker aspect to it too, because the church elders know that the people they visit are not likely to be receptive, and many of them will be outright rude.
Debriefing the returning members is a big part of the process, and helps to reinforce the idea that the church is warm and welcoming, while the outside world is cod and uncaring.
Yeah we get Jehovah's Witnesses - I just let them excitedly tell me all about their beliefs for ages and pretend to be interested. Then eventually I will say something like - Well, that does sound reasonable - I will have to tell my husband about this.
They tend to fid an excuse to leave after that - which is at least one nice thing about them, some other groups - will tell me that my "lifestyle choices" are immoral and I will go to hell. Jehovah's don't - they just leave.
Solicitors in the UK are what you'd call lawyers in the US. And generally no, not in my experience. I think I had Jehovah's Witnesses around once 20 years ago.
