I assumed it meant 'totally against violence/war in any circumstances'.
I know a girl, friend of a friend, who claims to be a pacifist, she has a peace symbol tattoo etc. However last night this girl said that she is against war, except WWII ... because there was 'no choice'. Now, just for the record, my grandfather fought in WWII - so I am not questioning the actual war.
But I thought being a pacifist meant totally not supporting any war - not picking and choosing which ones seemed 'fair'.
She also has a Hunger Games tattoo - possibly irrelevant but just
