I think everyone knows what they mean when they refer to their own subjective experience. That is entirely separate from the question of what that experience corresponds to in the external world. If you put an object in my blind spot, I know that my subjective experience will be of no object. I couldn't make that statement if I didn't know what I meant by subjective experience.
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.
