There were two significant congregations in my JW experience. They seemed very different from each other, but maybe they weren't really. In the first congregation, I was a teenager, the only member of my family "in the truth." This congregation seemed fairly well educated and advanced for JW's. At the time, I was totally impressed with them because I was really stupid. There might have been just as much pettiness in this congregation as the one I was associated with later on, but I would have missed out on it because of my status as a "new one," without family ties within the org, and without access to the witnesses when they were dishing about the others.
The second congregation I spent several years at seemed to have a lot more strife, gossip, pettiness, downright meanness, ignorance, prejudice and downright poverty and despair, as well as more families with various problems. I was married to an elder, which gave me access to a lot of stuff I'd rather not have known. The elders were always sniping and gossiping in a way that I then believed was usually confined to females. It was the pits! I always thought I was sick. When I told my daughter about my imaginary illnesses during that time period, her response was, "Of course, Mom. You weren't allowed to say you were unhappy and that you didn't understand why life totally sucked."
Both congregations were probably standard JW congregations. How sad.
