Religion comes from cultural beliefs, unified dogma and their texts.
Views of Individuals and followers of religions that contradict their religion don't speak for their religion.
Some say that Vaishnavism is, others say Islam is.
Some say that no religion is the religion of peace.
Based on Scriptures which religion is the religion of peace?
In my opinion, Its undoubtedly JAINISM, just before Buddhism. A faith with the lowest or no violence whatsoever and texts that speak of all forms of intentional killings of any living being as Adharma.
Atheistic and open to reason.
A religion shared by Gandhi himself that made his belief in Non violence even stronger.
Other peaceful religions include Buddhism, Taoism, Confucianism, Neo paganism, Yogic Hinduism, etc.
If any other faith exists with peaceful ideologies, please do share and mention your reasons.
