Well that’s one way of putting it. A broader perspective on religion/ ideology in general might acknowledge that conscious beliefs are not as important as we sometimes think they are.
Beliefs are not as important as actions, either in personal experience and development, or for organisations as a whole. In fact a certain level of cynicism or detachment is probably healthy for religious or other ideologies to function smoothly. Religion really is all about actions. JWs demonstrate their commitment by ordering their whole lives according to JW routines and practices, not by mastering the Gentile Times calculation from the book of Daniel, for example.
Sometimes it can be a bit jarring to encounter older JWs who’ve given up education, careers, and families, blithely making jokes about Armageddon not coming yet. What are they thinking? Their beliefs can in one sense appear quite superficial and fragile, but decades of commitment and practice are strong testimony to their commitment that shouldn’t be underestimated. Actions speak louder than words.
Other religions exhibit, not identical, but similar patterns. Catholics for example, who make fun of the church, its teachings, even the pope, yet nevertheless insist on Catholic education and sacraments for their children. They may express cynicism, but their actions demonstrate commitment.
