Mr. Theo. I think you're your viewpoint about the mentality of most JW's is spot on. They view it more as "just something they do, or as a "good way of life". Many don't view the GB as having any sort of special communication with God or knowledge about the future and have no intention of making a life and death choice when it comes to JW conscience issues. Others are using the congregation or organization as a social network or as a refuge from the realities of life. As the song says. "every form of refuge has it's price" In this case the price is sitting year after year through mind numbing meetings and assemblies and pretending to go along, just so you can be part of a group.
My older, brother ( a regular door knocker, regular meeting attender and big time spewer of all the usual JW euphemisms ) admitted to me that he thinks most JW's, including himself, are pretty much playing the "just in case" game. They are hedging their bets by keeping a toe in the door and keeping their mouths shut about any doubts or disagreements they have. Each one thinking the other is genuine and none of them being honest about anything.
