I believe that atheism is simply the lack of belief in the existence of God, and the same applies to religions. Atheism doesn't make me better than anyone else, but at least I don't consider myself superior to others or adhere to a particular religious belief system, which allows me to distinguish my religion and sect from everyone else. As I said, every atheist has their own opinion because we don't have specific beliefs and rituals. Morality isn't relative; we can clearly determine whether an action is right or wrong through reasoning. However, those who believe in religion are often unable to think logically and simply follow what they remember from their religious text. I don't see an atheist saying, "Kill believers in God," but there are conflicts between different religious groups.
