I have never doubted that people have "faith", and I'm also well aware that religion and faith are two wholly separate things.
I also have no desire to "ban religion", and nor do I doubt that even were it to be banned, people would still practice. There is, after all, historical precedent for this even in the UK.
I'll just reiterate, it is clear, to me at least, why religion frequently attempts to monopolise morality, and declare itself the origin and source of morality, as if it is something that humans required to be "taught" instead of something that is innate. If you take this as read, it follows that if you remove this moral authority, humans will regress back to an animalistic state, whereupon they are incapable of behaving with any sort of human decency whatsoever, therefore, it is imperative that humans retain their religiosity and religion persists.
The problem is though, that simply isn't true, because there are plenty of examples of non-religious or atheistic humans still behaving with perfect human decency when religion is completely absent. So it's clear that human decency and morality is not dependant on religion and religiosity at all, and therefore any argument that posits this as a reason as to why religion must be preserved is nonsense.
I'm not saying "we need to do away with religion", I'm merely demonstrating how "we need religion to stop society falling apart" is baseless nonsense.
