This is a hypothethical, so I'm not looking for whether you would ever do this, or "why would you want to subject yourself to this...", but rather, what would happen if some DID do this....
...................
You're half of a married JW couple, and you admit to doubts about certain WTS teachings and it leads to an eventual disfellowshipping. But instead of walking away from the Kingdom Hall forever, you stay put. You faithfully go to every meeting with your spouse. You attend every CAD, SAD and DC. You underline your WT, you sing the songs. You don't roll your eyes, or huff and puff at crazy stuff said from the platform or read from the publications. You act like nothing's changed accept that no one is able to talk to you. When the meeting ends, you don't skulk off into the parking lot to wait in the car-- instead you sit quietly in your chair and read your Bible until your spouse is done associating. You make no efforts at reinstatement because your beliefs haven't changed.
You would be a living, breathing example of everything the WTS says apostates aren't. You don't act angry or bitter, you don't picket outside, you don't try to convince others of your beliefs. At every single meeting you sit there as a reminder to your spouse, the elders and every single person in the Kingdom Hall that the only reason you are being treated this way is because there was a certain doctrine you did not believe in your heart.
Your spouse would see that you haven't changed or become some evil "mentally diseased" person. Those who are shunning you will see (and hear from your spouse) that you haven't turned into some venom spewing apostate demon. Call it civil disobediance, J-dub style...
What would the long-term effect be on your spouse, on the elders, on every single person in the congregation?
I'm curious to hear everyone's thoughts...
