I'm of this so-called "class." I have suspicions on two others as well.
I can post my exerpiences/feelings of being part of this class or group.
-it's so true that as you realize that your kh friends are conditional on your religious agreement you really begin to distance yourelf. Why would I want to be close to people who don't like me for me but only for what I believe. I'd much rather make worldly friends that could care less about my religious feelings.
-fear of being found out. I've been fading (became a member of the class) since 2002. That's a long time to research, analyze, ponder and decide matters relating to your faith in God all by yourself. Yes, the internet has made all of this possible, but I'm still alone with my thoughts most of the time. Healthy non-witness friends make a world of difference in going through the process of exiting. Not friends that tell you how screwed up you are or how you should believe, but friends who will just listen to all the small petty jw issues as you wake up to freedom.
-fear of being found out (again). Imagine everytime you comment at the meeting, give a talk or just have a conversation with a true believer you put yourself in a position of slipping up. Perhaps you use the wrong term, you know dubspeak is very specific. Perhaps you haven't been studying for the meetings and not really paying attention so that the newest light escapes you. In a conversation that can have embarrassing and very serious consequences - especially if it happens to one or more people or on more than one or two occasions. Giving talks is the easiest because all anyone does is research the cd rom and sort of put it in their own words. But, while you're up there you have to keep your mind sharp, if you slip up - you're dead (figuratively).
-Once you really don't believe anymore but you continue to associate for whatever reason you run the risk of not realizing how weak spiritually you really look. The society knows the signs to look for and the elders are well versed in this. Has your commenting declined in amount, perhaps quality?; has your field service time dropped?; do you get to the meetings as early as you used to or stay as late as you once did?; do you miss meetings more frequently than before? especially bookstudy?; do you maintain the same amount of social acitivities with those in the hall who are/were your close friends?; there are more but you get the point.
As the one living the double life we don't always realize how we appear to others. That is dangerous and can really trip up a fader. They label you as weak; then you start getting sheperding calls; if you still don't respond and your body of elders is zealous you will get more and more attention. They want to bring you back, but barring that they will punish you.
-living with believing family. Imagine the entire family as believers. Everyone reads and studies together. There is a family study in which everyone participates and enjoys time together. Then all of a sudden one of the mates doesn't believe. Your entire foundation is gone, wiped out. The believing mate is torn apart. If that believing mate goes to the elders or others in the hall to get advice (either to answer unbelieving mate's gripes or just to vent) the cat is out of the bag and the fading plan is out. You then cannot live two lives.
-if you have children, watching them get indoctrinated makes your stomach turn. If you come out against everything then the believing mate will get doctrination assistance from the local congregation and family (if any are dubs). If you do nothing you run the risk of the kids being totally brainwashed while you stood by and watched. Watching your kids brainwashed slowly and knowing that the outcome will be a hatred of you and your beliefs is maddening. Some go through all of these things just to slowly and quietly undermine the indoctrination effects.
All of this makes for a stressful life. For most, including me, it can only go on so long. Long enough to show your mate that you are a good, honest and loving person who will treat them with the same, perhaps better, respect that you did as a believer. Perhaps for some they do it long enough to get small children past the age of easy indoctrination.
I believe classes like this spring up in every totalitarian regime.
