Perry said: I see no reason why we as ex-witnesses can't make it our business to equip ourselves with certain questions that the WT cannot answer and be ready to share these with witnesses that we "happen" to run across. It only makes sense. There is no down side....everyone wins.
Perry, many of us do this. A few months ago, I phoned Brooklyn Bethel and asked to speak to someone about the blood doctrine. I had a copy of my project in front of me and the duffus on the other end was unable to give me a rebuttal for any of the arguments I gave him. He simply mumbled something about 'if new light needs to come about on this, Jehovah will bring it through the F&DS'. End of conversation.
The problem with what you're suggesting, is that if you are in a DF'd or DA'd state, most Witnesses will not speak to you and will look through you as though you do not exist. And they almost certainly will not engage you in debate about their doctrines, since we are all 'diseased' and possessed by Satan himself now. I believe that there are MANY Witnesses who go to extremes when it comes to shunning their family members for one of following reasons:
1) it somehow gives them a warped sense of 'loyalty' to the Organization;
2) they are furious with the family member for bringing "shame" on them by getting DF'd in the first place and have no problem with punishing them by shunning them;
3) they already have emotional problems and will use shunning as an excuse to treat their own flesh and blood as poorly as possible.
When my brother DA'd himself in the mid 1980s, I refused to shun him even though I was a pretty dedicated JW at the time. I could not see how ignoring someone could possibly be seen as being "Christ-like" and I would not do it. My best friend however, had no problem in looking through her DA'd brother, as though he did not exist and she and I had several arguments about it. In hindsight, I believe she reacted the way she did because her family was always very cold emotionally and fanatically faithful to the Organization. Typical background: her mom was the town tramp, her dad was the town drunk, they met, he got her pregnant (very shameful thing back then), they became Witnesses and in order to make up for past sins, they became "super-fine" Christians. I don't ever recall ever seeing any of the kids get a hug or a kiss or a pat on the back. Everything was: religion, religion, religion.
People like Lady Liberty and others have every right to be disgusted and angry with family members who shun them. Your idea of simply 'turning the other cheek', I don't think is very realistic.
