WOW. I am so in awe of what you're doing. I think you should be given sainthood status. The amount of courage and patience that must take....
I have thought about this idea in the past. It is probably the most effective way to help others out of the cult. Unfortunately, there are few with the intestinal fortitude and patience to carry it out. I get really nauseated just driving by the kh. I get goose bumps.
I cannot imagine entering that hellhole, seeing that butt ugly decor, smelling the eau-de-body-odor-pee-and-Lysol smell in the ladies' room, seeing faces of people I despise, seeing them with their smug grins thinking they won.....and worst of all, hearing the kingdumb melodies. I think I could stomach the talks simply by drifting off in my mind, but the rest...........it would be more than I could handle without telling them all off.
AND I would never tolerate shunning for one moment. I am not dfd so the moment they started shunning me I'd be in their face forcing them to talk to me. (heh, I can just see myself saying, "Hi Sister Shunalot! What a beautiful skirt you have on. It's really encouraging to see a sister adorning herself with such modesty. Would you mind going with me to the mall tomorrow afternoon? I've been in the world so long, I'm fresh out of modest attire. I thought we could hit a few stores and then have coffee at Starbucks. Perhaps you could bring your Watchtower so we could prestudy it over coffee, maybe get in a little informal witnessing too!" lol
On the other hand, I believe I have helped prevent dozens of people from joining the borg by educating them about the facts....and I've helped active dubs use their critical thinking skills....but this has all been done w/o entering a kh. Kudos to you!!!!!!!!!!!!!!
PS-What do you do about field service?
