but should we define every word within a discussion?
not really but kind of yes :D. Things like agreeing on what colors are colored doesn't require much discussion but even there you had the blue/white dress incident. I think it s import to define the big words Freedom, Democracy, Justice, The Left, The Right and a lot of other stuff will logically built up on this like.
In math it is the same you only have very view Axioms. Most rules follow as a logical consequence out of the Axioms.
it just becomes a blamegame
Yeah it is hard to talk about what words mean. The nature of language is more dynamic and social, like you said and while it is important to try to keep our understanding of words as universal as possible. It won't and shouldn't be something completely dictated.
