> words for things that don't exist

This is rhetorically slippery, and feels like it is restating the thing that I asked to be demonstrated when I asked for example of the opposite. It feels like begging the question.

In either case, the central thing that I was saying is that critiquing an article because it makes a claim about a specific word which also applies to an entire class of words makes that critique feel less informative. What I mean is that if there were an article that said "The Sun is not red" and the response was that redness is a concept of human minds, then I don't know if I would feel informed. If the comment is just limited to point that out, I guess I wanted to point out the limitation.
