Hi - By the sound of it you've got some verbal juggling to do if you want to avoid DF.
The question they asked me was something like: 'In your opinion, do the Witnesses present the truth, but that truth isn't for you; or, do you believe the Witnesses do not present the truth' (or words to that effect). 'Yes' to either = probable Judicial Committee, 'No' to both = more hassles as you’re not acting in accord with your words by being inactive.
I took an approach that suited me, but may not be right for others... I replied that I'd given that some thought and checked the dictionary definition for heresy and that seemed to describe the first condition they described. I'd also checked the dictionary definition for apostasy, and that seemed to describe the second condition.
I said that I didn't think that either condition described my position, but that I was acutely aware that my current thoughts were probably wrong and that I couldn't and wouldn't presume to trouble others with it. 'At the end of the day, I'm not sure where I'm at in regard those very serious positions you describe, but I remain absolutely dedicated to truth and goodness. I just don't know about those sorts of really big questions at the moment' (and what's wrong with any of that from the JW point of view?).
They left spitting that I was creating smokescreens to hide behind. True, of course. They don’t like people just walking away on their own terms. One of the guys was a buddy and when he called for a (further) follow-up call, I said that they were always welcome for a cup of coffee but I had nothing religious to discuss with anyone. They never came for another official visit.
That worked for me, but may not for others. I just suggest that you consider it from their point of view before they come and before you speak. Give them uncertainty and humility, but avoid any definite positions on anything, especially anything they suggest even if it sounds like it’s an ok thing to agree with – they’ve practiced this and have a clearly thought out strategy to find out apostates.
Easy answers to any question include: “I don’t know’; ‘I’m not sure’; ‘I’m sure I’m wrong’; ‘I’d have to do more research/prayer/meditation on that’; ‘I don’t understand what it’d mean to say Yes or No to that very deep question’; ‘I don’t remember’; ‘Not in my presence’...
Good luck, with clear thought and good preperation it's possible to get through.
Cheers, Max
