Dubs can't entertain the thought that someone would leave without being under demon control, because that's what's been repeatedly pounded into their heads. It's Black or White, Good or Bad, Jehovah or Satan, JW or Sinner. Only those not 100% indoctrinated can think for themselves, but even then a Dub must follow the crowd. They must at least appear to agree with the gossip or the suspicion will turn toward them. To be a Dub, you have to stay in Dubstep. I doubt everyone believes all the gossip, but it's too risky to voice a different opinion.
Don't forget how exhausting it was in there.
Not sure what my current fading "sin" is as I've heard everything from that old favorite Been Stumbled (well, yes, by elders who refused to report child abuse) to Secret Sinning (I wish my life was that exciting) to Apostate (okay, by their definition that's true). It's all good - if I can be their gossip fodder, maybe they'll be leaving someone else alone. And my family sees how much happier I am now than before my fade, so that's a huge plus in my book. Maybe that will eventually help them to wake up and get out.
