May I contribute to this as an outsider (not, never have been a JW)?
One of the reasons I enjoy this site is the opportunity to discuss religious issues. I tend not to do so in real life because (as an atheist) I would hate to be responsible for destroying someone's beliefs (though having learned what I have here I could ow probably make an exception for JWs and members of other destructive cults).
I was brought up as a fairly fundamentalist (in the UK, not the US, sense - there is a difference) protestant non-conformist. I was baptised at 13, left at about 15 - normal teenage stuff, discovered girls, etc.
I got married at 23 and a couple of years later my wife and I became involved with the local church ('going back' for me, brand-new to her). We got baptised together (yes, I had two!). We were enthusiastic and committed and I wanted to know more and more, so I started researching. t that time I believed that it was the most important thing in life, so maybe we should sell the house, give up my job, spend all our time doing good works, witnessing (no, it's not only JWs who do it!) etc. etc. In other words, live what we believed and really go for it. I shudder, lookin back, but my excuse is that I was fairly young then.
Actually what happened was that the research just threw up more and more issues and fairly soon led to a complete loss of faith. I was sharing the research with my wife, and - without pressure or persuasion - she came to the same conclusion.
I'm not a promoter of causing anyone to lose their faith, but I wonder what would happen in the 'UB mate' scenario (see, I'm even picking up the language!) if the UB one said something like 'I can see how important this is to you. Tell you what, let's really go into it, research, and once we're convinced, we'll sell the house and move somewhere smaller/not get that new car/furniture/redcorate/vacation and instead give the money to WT or whatever. I'll downsize my job so I can do more at home, and you can go out on the door2door a lot more.'
Or would that just be tooooo risky?
