I remember a brother being removed as an elder in the late '70s. He was my book study overseer and when he announced it to the group after the meeting, he said something to suggest that the reason he was removed from his position was because some people didn't like some of the things he said. I was young and didn't understand what he meant at the time. Looking back I recall people whispering about him believing certain ideas that weren't in line with the GB's teachings
He and his family remained in the congregation until one Sunday morning, a few minutes before the public talk was about to start, he had an altercation with a special pioneer and was forceably bundled out of the hall by a posse of elders.
This was a shocking incident and talked about by many for a good while.
He was never disfellowshipped, but even as a child I knew from the adults that we should have nothing to do with him or his wife and he was referred to as an apostate.
I never saw the family again.
