Most of us are so young we can only remember one very old jw that said they were anointed.
The perspective would be different if you had been a Bible Student in the teens and 20's when everyone was partaking and there was not a two-class system. The people you would see would basically be the type of people you see at the meetings today taking in consideration policy/doctrine changes.
They were not all "nut cases" any more than jws are all "nut cases."
Why is my perspective different, my grandparents were from that era as well were many friends of my family. While they had some of the personality issues we all have, they were definitely not mental cases.
