This is a very interesting thread and I have enjoyed reading all the posts.
The good which some religions do (such as promoting sensible moral values and by helping the needy) could also be dome by purely secular organizations, however without organized religion it probably would be much harder to unite people into having a common set of values in a non-totalitarian way. It would probably also be hard to create secular institutions which would have enough power to effectively resist tyranny and organized evil.
I agree. However I think the Jan 6th event in the US merely demonstrates “entitlement” (as the kids would say) rather than the collapse of democracy, in that particular case.
