I like your "Fuzzy But Not Ambiguous" approach to one of the most confusing DDD concepts. If I dare to summarize what you said in a couple sentences it would sound like this: "Domains and subdomains reflect our perception of reality. These perceptions could be very subjective and do not have to be consistent with each other or even internally. Bounded Contexts reflect how we formalize these perceptions in a form of models, which we believe, and could try to proof are internally coherent but do not have to be consistent with each other (for that Context Maps exist)."

I tried to make it one sentence , but it took me three :-).
