Now, I'd call it a quibble, nay, a perfect _cavil_. My point is simply about the distinction between the "social/discursive constructions" that involve oppression and those that do not.
That said, the difference here lies not only between nouns & adjectives. The language makes meanings in social use, in humans making transactions (affective, cognitive, practical, etc.) with not only other humans _but also the natural & social world_. You live in Florida -- how "meaningful" for you are different names for & fine distinctions of snow? Are they as practically meaningful to you as they are to residents of Aomori, Japan? I suppose that you don't take this "social/discursive" construction business too seriously when your polemical urge masters your brains.
