It takes a lot of those moments to experience a paradigm shift. Unfortunately a person usually won’t encounter enough of them to see clearly unless they’re actively searching for answers. That’s why churches discourage asking a lot of questions, or reading secular material. When my walls started crumbling it was a legitimately uncomfortable experience. Realizing that you’ve been living by a bunch of preconceptions that aren’t universal truths, and understanding for the first time how another group perceives something differently than your entire core group does, is really confusing and difficult. Most people get scared when they hit that point and retreat back to their core belief system. It’s very uncomfortable to keep pushing through for answers.
