Interestingly you're having the same experience as the person you are replying to, but you haven't reached the understanding they've reached.
If all those people you say refuse to question their beliefs are actually chasing a higher form of good for themselves, why would they engage in any kind of activity that would undermine that pursuit? It doesn't make sense unless you propose to replace it with a structure that is more strongly aligned to with the goal of achieving a higher form of themselves. Which nobody ever actually is when they argue against religion, they just got hurt by somebody's interpretation of it and are trying to find validation for that hurt.
