I see. I think we disagree on the contexts in which it is significant evidence against understanding the propositional content of that sentence. For example, I think being unable to taboo ‘utility function’ probably means one doesn’t understand it and that one’s use of it in sentences is confused. This is probably true of all philosophical or scientific terms of art. I don’t think this is true of ‘should’, or what you might call more everyday language. And I’m inclined to say that the tabooing or defining of such everyday language almost always does more harm than good. But thats a matter of details.

I share your understanding of our disagreement.
