Even though I was born in, my parents were inactive, so when I bought into the religion during my teenage years, it was almost as if I were a recent convert.
There was a young elder who took me under his wing. He, too, took the doctrine very seriously and we'd spend hour after hour discussing Watchtower teachings. That elder was disfellowshipped a month after I got baptized, though.
From that point forward, there weren't too many people, even elders, who wanted to engage with me. The vast majority of Witnesses would get very uncomfortable when I brought up doctrinal matters. Some even got angry. It was through social pressure that I eventually relaxed and learned that I was kind of on an island. I backed off for the most part.
Eventually I did find a few like-minded JWs, but that kind of "deep spiritual" discussion was largely unwelcome.
I think a lot of it coincided with Fred Franz's advanced age and eventual death. It seems that during the Franz era, JWs were encouraged to at least pretend to be Bible scholars, but that faded away once he was too old to hold any influence. Things started to dumb down considerably staring around 1990.
