In my later years of being in, I never pushed JW doctrine at the doors, I usually elected to go by myself, only on rare occasions did someone ask to work along with me, even then I simply got a conversation going and talked about the Bible and listened to the H'Holderand left a couple of mags or a brochure as a way of ending the conversation.
If I was with a companion, I would studiously write down all the info about the "call", but I never went back.
In early 2007 I stopped going in the DtoD work because I had come to the conclusion that the 1914 teaching was simply not in scripture at all,I did not get hung up onthe date 607 BC or anything like that, I just read Daniel and could see that the whole doctrine was pulled out of someone's arse.
Less than a year later, despite all my family being in, I walked away for good.
I don't see that you will have a problem with DtoD if you use my method, I will be surprised if you stick to the whole pointless waste of time for long though.
A lot of people hang on in the Borg thinking they will help family to get out, How exactly? If you haven't made it out yourself you cannot lead someone else, you are not free to speak what you know, carefully phrased little thoughts are brushed off by JW's, they don't think about what you say, so how can you make a difference to family by "hiding your light under a bushel"???
