I think a slow fade to "weak" is probably best.
That way you avoid the drama/shunning of DF or DA which is essentially the same now. I know it's hard for some because of the disgust we feel toward the org and many of their practices, but contolling our impulses is best for us in the end. It preserves our name and family connections.
I am also of the opinion to use the "theocratic warfare" tactic of telling the elders whatever you need to in order to remain in "good standing". It's done in the legal profession everyday.
Claim "discouragement", "depression", "health issues", etc. Play whatever card you need to to get them off your back. Do your protesting anonymously (in forums like this one) and watch your mouth in front of dubs.
There are a lot of moles out there that would love nothing more than to run to their favorite COBE and be the teacher's pet ratting you out. We have an entire family of moles in our hall that constantly have their eyes and ears open and troll social media.
If you do say something that comes out later and bites you, never admit to anything. Say "they must have misunderstood me, I would never say such a thing..."
Never Ever Ever Forget the Two Witness Rule. I can't overemphasize how big this "two witness" thing is. I have seen people get away with big acts of wrongdoing that happened in front of 6 people. This was because only 2 people would come forward and then they couldn't keep their story straight when the accused started getting nasty and throwing the "slander" word around. People crawfish big time when the heat is on them. If there is only one witness and you deny it, it can't go anywhere to begin with.
Honestly unless you plaster your face all over the internet screaming against the GB, it's hard to pin this stuff on you without your admission/confession.
So in other words lie. Lie your little head off. These goofballs don't deserve the truth and can't handle the truth.
Also despite what you hear on this forum from some, many elders are lazy and stressed out and don't have the desire or energy to chase you all over town to try and DF you. Now granted some will, but not as many as you might think.
Oh, and I am currently still serving as an elder. I am doing a surgically slow fade because of the wife.
