Language is an essentially public phenomenon. But that's another issue.
it isn't possible to obey a rule "privately" because there is no distinction between thinking you are following a rule and actually following a rule
rules for the employment of linguistic signs



In the case of snow, the position "snow is white" or "snow is black" is equally valid, but if you are viewing it in the context of "what is the colour of snow", with the obvious wildcard of the truth, then the position "snow is white" is more valid. In cases like these, indeed all cases, (I say that absolutely only in the context of relativism), the actual position and the context to which it is applied are separate entities. In objectivity, its the difference between n+1 dimensions (in context) and n dimensions (out of context).
What the relativist says is senseless because relativism undermines meaning by allowing the same proposition to be entertained as true and false at the same time by the same person

If you refer to out of context, then validity is equal and irrelevant, as quantifiably, it is 0.
propositions are not fallacious, only arguments are
