religion is supposed to help with self improvement and help people live together, build a community. what else is there? if religion does not achieve that, then what's the point?
humanity should continuously improve our society. globally.
we progress scientifically, and we should (and do) progress socially. the latter is the purpose of religion. every religion, when introduced, has induced social progress. if a religion is no longer serving that function, then it's time to move on.
