Most people are of the opinion that religion has caused more harm than good in human history. Religion divides man and nations even families are torn apart for its sake. In the past, many people were killed and persecuted for religious sake. The story have not changed much in recent times. It is so unfortunate that religious leaders only preach peace and unity after crisis or when they want to stop war, persecution, hatred among others while in the true sense of it peace and unity should be a daily doctrine.
Religious leaders cannot effectively preach peace and unity without preaching religious tolerance. That is the reason most of them avoid it. They want to convince people to join their religion even if they have to make them to hate their neighbors. That is the reason some people choose to be atheist because they cannot hate others.
It is unfortunate that we ignore the part of the scriptures that should unite us but chose to dwell on those scriptures that will divide us. The Golden rule is golden for a good reason. It is the only law that is given to all the prophets across the ages. That shows that the golden rule is the sole aim of religion in its true spiritual sense. The religion of the new age should be more on uniting man than on dividing man.
Virtually, all major religion in the world and others less recognized religion stated the golden rules in different forms. Most of the followers of the various religions are either not aware of its importance and values or they have been brainwashed to ignore it.
