First of all, let's get this straight. No term is universally uttered, but that doesn't prevent people from referring to the universal usage of terms because it is well-understood that universality refers to the totality of the population that speaks a given language. The societal usage. The term "yes" is not used by all human beings, but all humans who use "yes", do so in the affirmative, and not the negative. Trying to argue against a term being universally uttered is intentionally missing the point.
See, this is the problem. You even concede the fact that this term is "habitually" used in a negative connotation. I back this up with descriptors from dictionary definitions to depict the societal usage of the term. All these two show that, in the english-speaking society, the term "chauvinist" has a negative connotation. With your concession, that really should be the end of the debate right there. Yet you argue that because you, allegedly, did not intend to use this word negatively, that there is a separate definition that is attributed to your usage, one without the typical negative descriptors. There are a few clear problems for this assertion. The first is that semantic internalism is extremely unpopular in philosophy of language right now, and for good reason. Putnam's Twin-Earth thought experiment is a good illustration of the problems with that theory. So it is a bad theory to just say "meaning is in the head." Secondly, that would lead to unreasonable conclusions for language from a practical sense. Because you're not merely arguing semantic internalism, you're basically arguing that whatever you say not only originates solely from your understanding, but also that others should understand terms as you use them to mean what you wish them to mean when you wish them. Not only could any given person use any word previously known as an insult as a neutral or even as a compliment, any person could use any word to mean almost anything, so long as he meant that when he provided the content, and put forth that particular "usage" of the term. But that would nullify the entire point of language. Language is conventions, accepted habitually, by which we communicate with each other. If each person may ascribe their own convention at the point that they desired to, then there would be no relatable conventions and language would lose its communicative value.
What the hell is a "positivistic linguistic purview?" First of all, it would be a "theory", not a "purview." Secondly, perhaps you know some philosophical theory that I don't, but it honestly sounds like you just made that up. No. I'm not arguing for the possibility of a model theoretic language. Not because there isn't the possibility of assigning T/F values but because of Putnam's Model Theoretic Argument against Metaphysical Realism. I don't know what else you could mean by "positivistic" linguistic theory. Semantic externalism does not require a model theory of language. Neither are you going for some skeptical argument to the tune of "meaning is unintelligible", you're presenting your own theory of semantic meaning. It's just not a well-developed theory, using a lot of vague language like "...subjectively apply to the semantics and pragmatics of those utilizing it." Is that semantic externalism? Is it making different claims, perhaps slightly stronger claims? No one would be able to tell.
Here's what has fundamentally happened. You called Chinese people chauvinistic. How are you even an authority on that? You probably aren't. Anyways, I called you out on it. Now you're trying to create some complicated argument to say that chauvinistic actually doesn't mean what society uses it as.
