If you look at history, polytheistic religions (for those not in the know, a polytheistic religion is one where you have an active pantheon of more than one gods and goddesses, who often symbolise and/or controls a particular part of nature) have generally remained very peaceful in their tenets and teachings. They may have gods that wage war among themselves, but an overwhelming majority of these religions don't teach/prescribe killing/destroying the unbelievers. And in cases where they do, it's generally related to a sect that worships only one god. For example, the ancient Egyptian religion does not, in any way prescribe violence against other religions. But conflicts often occurred between people and priests who believed in a single god, not the whole pantheon. So why does it happen? Why are monotheistic religions/sects of polytheistic religions more violent towards believers of other religion/sects? What are your opinions?
