It has been pointed out that the Syrrannites possessing weapons and being skilled in martial arts is inconsistent with them being pacifists. However there are different degrees and forms of pacifism, there are extreme forms that believe violence is unacceptable for any reason. But there is also the pacifist philosophy that believes the use of violence is acceptable for defense, but that it should only be used as a last resort. This appears to be the type of pacifism the Syrrannites practice, as it is in line with Vulcan beliefs seen in the future. Vulcans such as Spock and Tuvok have stated that Vulcans recognize there is logical use for violence, even if they find it distasteful.
