I'd like to think a was one of the "good JWs" for the bulk of my association with them. I was on a high-horse for the first year or so, though. I was a teenager then and I relished the opportunity to argue points of doctrine with religious householders.
In hindsight, it was in extremely poor form. A 16 year old kid arguing with grown men and women about things I had very little knowledge of. Ignorance was bliss, however.
