As a specific example. If I ask the true/false question "Have you stopped murdering people?" an entirely valid response is "that question is wrong"

It is reasonable to map the world in binary logic. but the map logic must be correct and raising an error when it is not is important.

The crucial point here is the difference between response and answer. Saying that the question is not applicable because you never started murdering people is a response but not an answer to the question. And that response answers an omitted binary question, is the actual question applicable in the current context, is the implied assumption - you started murdering people at some point in the past - satisfied?
