at least for many....
I remember looking around at meetings and so many in the audience seemed to be in another world. People would get up and talk at the back shamelessly. Meetings were a good opportunity to make plans with friends. Service? Get a fun car group, preferably in a minivan and get a bunch of return visits lined up, hopefully at opposite ends of the territory, and take a good long break. It really isn't so bad, lots of laughs, very little interaction with the public, perhaps leave a Watchtower at a "good-time Charlie" call in which the householder has established a friendship of sorts with the publisher but obviously couldn't care less about the literature that's been left for the last 10 years.
I took it so seriously for so long. Studying anything I could get my hands on, researching old publications, analyzing each and every verse of the Bible. I think I was the exception. Most get a cursory outline of beliefs, most of which they could never backup up on their own, and carry on in blissful ignorance. Most are clueless about the real history of the organization, just how completely whacky some of the beliefs are. It's Jehovah this and Jehovah that. Revelation? Daniel? 1914-1919, 1922, 1926, 1938, 1944 - all identified as prophetic years? Most have no clue let alone being able to show something from the Bible proving these dates.
What holds the vast majority in is the social and family aspect. How many of these people would leave their worldly circle of friends to join at this point in time? Not many. But once you've been in for a while and it's become your world, it's scary to contemplate life outside of it. So they hold on, not really thinking, perhaps having a vague sense that something isn't right, but just shuffle along.
I think proof of this lies in those that have accepted the overlap generation teaching. It probably wasn't even noticed by half of the mind-numbed attendees.
Like that governing body member said during the 1980 shake-up at Bethel: avoid deep study of the Bible, get a hobby. Thinkers and studiers are the Watchtower's enemies.
