rebel8, good point. Of course I knew that scripture, which says "whoever says a greeting to him is a sharer in his wicked works" and another that says, along with not eating with them, "Not even saying a greeting" but I thought of it as, Whoever initiates a greeting, whoever goes up to them and opens a conversation with them. I wasn't intending to stand there and engage in a long discussion. If I had dropped by book and a DF person picked it up for me, should I not say "Thank you" to that person? (I am sure most witnesses would not in such a scenario.) All this is the way I apparently understood that scripture from the very beginning, although I never really thought about it or discussed it with anyone. I spoke and acted from my heart. My conscience was my guide.
To ignore the person's greeting would by extension imply I have determined that the person is not worthy of my greeting and that the ransom has not yet covered that person's sin. I believe that's what these witnesses feel, that Jehovah hates this person and they are not worthy of forgiveness unless they jump thru hoops in which case the elders get in between the person and Jehovah and try to get Jehovah to change his mind about destroying them.
The underlying principles should be Love and Mercy.
