2. Centralized religion may be in decline across much of the world, but that doesn't mean all the ingrained beliefs and associated behaviors are linearly declining along with it. What I see are people adopting new systems of beliefs that replace their religious foundations while keeping many of the associated behaviors intact.
For example, a core aspect of most of the practices of Abrahamic religions is sin followed by guilt, shame, forgiveness and, sometimes, atonement. This process doesn't just disappear, it has inertia that often survives apostasy. I pointed out this process is open to ideological 'hijacking' and replacement by new ideologies which keep the process in place but alter the individual's conscious rationalization for that process's existence.
