I know what they are supposed to and or claim to be, all religions seem to attempt to promote some type of peace or unity. But as someone on the outside looking in the aren't peaceful. You don't have to make physical attacks to be considered non peaceful. Edit - there's also the rule of without saying. I'm breaking that rule by saying it but if you have to tell someone what you are, then there's a high chance that you aren't what you say you are. Like people that run around going "I'm crazy as hell, like for real" or my personal favorite "I'm not like most girls" - most girls.
