Few active JW's understand the actual theology.
They grasp broad strokes and few details.
It is enough there is no hell and no Trinity.
It is enough they aren't passing the plate at the meetings.
It is enough they are in an "ARK" of salvation.
The devil is in the details.
For example, you know how to make a phone call, but, can you really explain how punching buttons on your cellphone is able contact another person across town? It isn't important to you. You just "know" it works and ignore the technology.
Same with the "deep things of God". It is enough to "know" the Governing Body understands and that it is written down in some publication somewhere.
Keep this one fact in mind about Jehovah's Witnesses. They exist in three parts throughout their history.
1. Honest bible students attracted to the gimmicks of Russell (charts, graphs, chronologies, pyramid inches, etc.) expected the End of the World to come and they wanted to know more.
2.Contrarian hard heads under Rutherford wanted to prove everybody was wrong about everything except themselves. If Christendom said "white" they would insist it was "black." Holier than thou was the name of the game. Proving you were right and righteous consisted of provoking demonstrations by refusing blood, going to prison, refusing to celebrate this and that.
3.Professional ministers under Knorr performed an education work consisting of explaining the deepest details of scripture by persuasion and indoctrination door to door. They were clean cut, honest, hard working and able to win every religious argument by flipping the onion skin pages of their green bibles.
THEN the1975 debacle turned their squeeky clean image into cult brainwashing crackpottery. Everybody was stunned quietly into silence.
The governing body regrouped. Splits, cracks and rebellions were fomenting underground....even at Bethel!
There was a schizm. The winners were the harliners who performed a slow-motion INQUISITION to shut apostates up and kick them out as fast as they could.
The crackdown rivalled what happened when Stalin got rid of Lenin and the purge got deadlier and deadlier. The only people who remained kept their doubts to themselves and their mouths shut.
Brothers and sisters started living double lives. They got their best acting faces on at the Kingdom Hall and cut loose privately.
Three generations (from 1975 onward) of JW kids were reared by despot parents who drove them nuts and pushed them (unwittingly) out of the "Truth" by squeezing the fun out of life.
Other parents, who were in silent despair, faded or acted out along with their kids. Thus, in a latter day Seppuku--tens of thousands of once faithful JW's committed ritual suicide by getting themselves disfellowshipped.
Today, at your local Kingdom Hall you don't have curious human beings with live and rational functioning brains. You have trained monkeys who put on a show of acting as though they are learning. It is just a performance, I assure you.
