I said as much to an elder I knew during my exit.
The response I recieved was rather frustrating, which is to be expected. Basically he stated that even though some congregations act this way, it is not the way they should be acting. Our conversation was mainly focused on appointments (MS, Elder), and how some BOE discriminated against people who did not "do enough" of the right activity, even though they may be excellent in other areas.
He gave me an example of how his own BOE broke against this trend.
The facts he presented (as typical of most conversations with JWs) was merely anectodal. The social atmosphere of the JWs is cultured by the magaizes. While there is no "official" policy that states everybody should have the same attitudes, the outcome is there. Because the WTS bangs into peoples heads that certain forms of activity are required and essential (and subsequently, not done by "lazy" and "selfish" people), an atmosphere is created where the members link the two ideas togeather. e.g. "Jim is lazy because he does not do enought preaching".
But this cynical atmosphere where structured activity is equal to "spiritual growth" is an outcome, and therefor harder to document and prove.
