Your basis for discussion is that you read the wiki article on common sense? Then you cite a dictionary definition? Suffice to say that is pseudointellectual and inappropiate.
And then you obviate the concept by rendering your own gross ignorance: people don’t like pain? Today you learn about masochism. People need entertainment? Monasticism, asceticism, Buddhism, nihilism, et al. People learn as they age? Quite unfortunately many studies show many people lose a great deal after their teens. And your invocation of the idea that cultures share morality such as a prohibition on murder (this has nothing to do with “reciprocity” by the by) is truly divorced from basic observable reality.
