I doubt anyone will bother to DF me when I haven't been to a Kingdom Hall in nearly 7 years, anyway...they have bigger fish to fry I'm sure. I vote, I celebrate holidays, I believe in evolution, I don't even take the Bible literally and I'm pretty free in discussing how I USED to be a Witness to anyone who I might get into a discussion about religion with. I pretty regularly steer people away from the Witnesses in my every day life, especially when it comes up.
I'd kind of hate for my parent's sake for me to be DF'd, though. They're pretty old and not too well, and even though I live 1000 miles from them and we never discuss "the truth" by phone, I suppose they assume I still do some things Witnesses do or don't, although they know I'm inactive and don't attend meetings. I don't lie to them about that and they quit asking quite a while ago.
I'm happy to just keep letting them assume. I'm sure they won't shun me entirely...they didn't shun my brother when he DA himself. They're not active Witnesses either, but are still pretty careful to observe the JW don'ts if not many of the do's. I'm sure it's their own fear of being DF that keeps that going, especially for my dad. My mother was always the one that was really into it. My dad...just along for the ride for quite some years now.
I have no one left to offend by not being a Witness anymore but my mother, really and an aunt that I particularly like, but not wanting to distress elderly ladies in ill health (and it would) is a good enough reason to be a "fader" for the time being.
