Thanks for the backing Gordon...
my whole belief is that we (that is ex JWs, inactives, or in my case DF'd JWs who have JW family members) should not let them (JWs or the Society) dictate the terms of our familial relationships. If we sit back and wait around for them to come into our lives they are not going to do it (some will but these don't usually leave off associating in the first place). There are a lot of reasons for this as we all know and I think the loving and kind thing is to be sensitive to them, even if we don't agree with them.
I believe that it is helpful to burst the bubble of illusion that life is only happy and good as a JW. Thus the more that we share our lives, without a direct confrontation over our religious differences, the more that illusion is pierced. The more and more they, JWs, begin to consider that there are alternatives to having a happy life. I think that approach is more useful to eventually penetrating their defenses.
Yes as Nic says being a JW is a major part of their self-identity and ideally sharing and communicating, even discussing such topics as religion, faith, etc. would be a normal and natural part of our relationship with JW family. But we all know that is not the case (for most JWs) at the present time. I also think it is disingenuous to complain about not being (preached) to by "cult" members.
The fact is that when it comes to our JW relatives we can't have our cake and eat it too. Under present conditions, JWs are not completely free to make the choice to associate with opposed-family members without consequence. This is wrong but it is reality and to ignore this reality is to simply be selfish.
If our relatives do tolerate our association, even if we be opposed or in conflict with some or all of JW religion, we should make the most of the opportunity to do so. There may be times when we can challenge things more directly and I am not one for backing down or holding one's tongue in the face of outspoken falsity. But one need not deliberately seek to stir up conflict or provoke discomfort just for the sake of it. (Personally I don't consider that to be imitating Christ's example.)
It isn't going to work in every case and there are some JWs who won't even give their non-JW family a chance. That's too bad but its no reason not to continue to try. I happen to believe that it is possible to love people into reason and truth and even if it doesn't happen it is the way to be IMHO.
