A few trends among JWs I have observed consistently since the 1980s.
1. They know less and less about their doctrines.
2. They care less and less.
3. They go on the ministry less.
4. They take it less seriously.
5. They talk less and less about paradise.
6. They act less and less as if they believe Armageddon is coming soon.
Just when you think they can't get more apathetic and unenthusiastic, they put it down another notch. It's not the religion it once was. Vindication of what? Sanctify the who? They don't care.
