Dialects are established collectively. If I like your new word/dialect, I use it. That is the consensus. Wars are established collectively. Nobody fights a war as an individual - always as a group. Just like language and dialects are assumed at the individual level, through collective means. The rights of cultural groups, composed of individuals, to compose their own language, is the basis of civilisation. It is also the basis of war and that is the quandary - because it is not as dialectic as you imply (black/white). Its a balancing act - as you have indicated. Enforce cultural mechanisms (language) through violence - war - and you will encounter resistance. But give people the opportunity, at the individual level, to assume whatever cultural positions they may, using language, and you attain peace.
