I am absolutely fascinated by the answers here. The four of us on this thread (so far) who were never baptised dubs all suggested something other than using doctrine. Everyone else (with the exception of Franklin) suggested using it. Interesting indeed.....!
Because I was never a baptised dub, I can say that I certainly feel more comfortable using WT misdeeds - and for the exact same reason bebu mentions - because all the misdeeds are related to JW doctrine - and specifically, point to the evidence that the WT can not possibly be the F&DS. IMHO, everything crumbles from there. But I can also agree with Nathan that it can completely depend upon the person, the circumstances, etc. In fact, I thought of putting that into the original question on the thread, but I have a tendency to make things a bit more complicated than they need to be. So, this is definitely something I need to be aware of.
At any rate, thanks for all the replies so far! I'm going to be using this feedback on my jw mom and step-dad who are coming to my home this weekend. They are coming out of hibernation - specifically to address the e-mail I sent them (link below) - so I guess the circumstances I will be finding myself under will be directly related to UN Issues. Man! I hope they don't throw any doctrine at me, 'cuz it gives me a headache when I try to unravel it!!!
