When you say, "I know what I mean by subjective experience, and no amount of linguistic hair-splitting will convince me it doesn't exist", you are not simply saying you are perceiving X and that, even if X is an illusion, X at least refers to a persistent and predictable illusion, and so you know what you mean by anytime you refer to X.
You are actually saying is that X corresponds to something real, that you are directly perceiving some aspect of reality, because how else could you conclude that nothing could convince you that X doesn't exist?
It is to that, that I say no, you don't know what you mean by subjective experience.
