People who are violent and dangerous are only about 10%. The 90% cannot be irrelevant. It is the 90% that defines what the world is today...regardless of what the 10% does..
My OP is about how religions over the centuries have taught and enforced discipline, self control, sacrifice, charity, non violence, universal brotherhood etc. etc. That fact does not change. They have also been a major factor in unifying people.
Even taking just Islam itself as an example....leaving aside the jihadis, extremists, politically motivated persons and others....there is universal brotherhood among 1.5 billion muslims worldwide.....including India, Indonesia, Malaysia, Saudi, Pakistan, Egypt etc. etc. Millions of people in such diverse and distant places could never have shared a common philosophy or belief or culture without religion.
Likewise with Christianity,Hinduism, Buddhism etc.
Religion has been a great unifying factor and a great disciplining factor. No doubt about that.
The very fact that many people today are mentally developed sufficiently so as not to need religion any more to be disciplined or selfless or altruistic or non bigoted.... is due to religions and their efforts over the centuries.
