When I left the religion, I walked away and did not get DF'ed or DA myself. In doing so, my wife left the religion at the same time. In our life we have been very nonWitness in our life. We have disowned Christianity, and practice Shamanism. We celebrate every holiday for Pagan reasons and are deep in martial arts. So a lot of people ask, how come you have not been disfellowshiped?
When I was a elder, which is what I was when I left, I knew the answer to this question and still do. That is why I handled things the way that I did with being inactive. The thing is, elders are suppose to take care of the congregation. So anything separate from the congregation is not their business. They are only suppose to disfellowship people who are wanting to attend or who were active when they sinned and did not show remorse, basically they live a life that is not in line with their rules. To the point, follow the rules or get out. If you left on your own and did something, they honestly did not care ... as you took yourself out on your own. Now I am not saying there isn't a few zealots out there that do not know this info and go after everyone like they are the police, as we had someone like that too. The thing is the CO removed that person for wasting time on matters that were not productive and he is now out of the religion ... basically, he wanted power!
So if you walked away and you worry if they might hunt you down some day and DF you, don't!! They really do not give a crap any more then you do. My wife and I have been turned into elders of 3-4 different congregations that we know of, by people who wanted us DF'ed and none of them did a thing. In fact, the last time they were down right bold in telling the family members involved to drop it and leave it alone.
Just my thought
