I faded and that is what I recommend to others...You are right though, some people are so angry (understandably so) that they are not able to contain it and they say and do things that are not in their own best interest.
Ultimately, it depends on what people want the outcome to be. I am a 4th generation JW, so there was a lot for me to lose if I was out with it all. I wanted to maintain contact with my family, so I faded. And I moved out of my old territory and never contacted the congregation where I now live.
I would advise people who are fading and who do not want to appear as a threat to their family and friends to keep opinions to yourself, and to be encouraging to them as people. If something is important to them, be happy for them, encourage them. It does not imply agreement or consent. It just means can love them just as they are with no expectation they will be different.
That said, if you have family who are mean or abusive to you - then keeping your distance is probably wise.
Get into therapy. Fight the training that "everyone is dangerous", quell the paranoia and start building your social network outside of the congregation so when you fade you have something to fade into. That was one of the hardest things for me to overcome - having no social support in the congregation and no social support outside the congregation.
You might find a group in your area like Sunday Assembly. Lots of people like you and me there and it is a wonderful group to fall in with.
