this desperate and too oftenly parroted counter-argument falls flat on this charge by two very elementary accounts: a) correlation doesn't imply causation, and b) the well-being itselfIn communist and fascist societies, removal of religion was by force not by choice. Result was disastrous because of that and especially because reality of fascism and communism is totalitarianism.
In Nordic countries such as Sweden and Denmark, for example, the most irreligious countries in the world where religion plays no part in public life and where religion was cast out by choice, these countries are doing great and consistently and constantly rank highest in life expectancy, child welfare, literacy, schooling, economic equality, standard of living and competitiveness in the world.
All I hear are crickets from your part. Perhaps that is your complete disregard to nuance.
If you need a god to tell you not to cheat, steal, or kill then there is something clearly wrong with your mental balance. You do not need a religion or some fictional deity to lead a moral life.
for a start, you must demonstrate that a) 1) atheism which you claim is closely associated with the nordic people (which is false, but granted for argument's sake), and not the church which is closely associated with the nordic states, yielded the (well part in) well-being of the nordic people, and 2) how has atheism, being closely associated with the tried-and-failed communist anti-religion/anti-Church regimes, not yielded the known opposite outcome e.g decay, oppression, death and destruction, and b) whether said well-being does account for the individuals suicide-phenomenon and for the long-term well-being of society (e.g although the titanic was looking great it was in fact heading towards its destruction), in which case, you must demonstrate that the church or religion, and not atheism or an atheistic belief, is yielding the relatively high suicides rates when they exist (as is currently the case), and that (or how does) atheism, as opposed to the church or religion, secure the nordic societies' a long-term well-being
