I mean, if you wanna break down to the most obvious possible facet to disprove 'Sharlayan is pacifist', remember that we have two different combat jobs from Sharlayan. That puts them ahead of several nations in the game that confirmably were in wars! And yeah, they're both healers, but both were explicitly mentioned as being combat-oriented, we're not looking at 'parlor tricks that happen to be able to draw blood'.

Again, as I said: they're isolationist, not pacifist.
