You asked what was going through most Witnesses minds....let me help:
Almost nothing about their religion.
Most of them are so uneducated it would shock you. They don't study, the greater majority have never read the Bible, much less their own literature. They are caught up in a repetitive schedule.......it pacifies their minds that they are doing something good......
To test the theory, ask one what happened in 1919. Most of them have no clue.
They are thinking about bills, work, stress, gossip, hiding their drinking/porn. Almost none of them think about anything deeper than what outfit to wear when it comes to a District Convention.
