I didn't "miss" anything. What is "rational" to you is often "Greek" to the rest of the world.
Still don't see the dots you're trying to connect, or how you arrived at "because I said so", which is your idea, not mine. If you want to run a series of rule clinics during your games, that's entirely up to you. When asked a civil question, a civil, concise and clear response is appropriate. That is simply not an open invitation to engage in a prolonged debate, unless of course, a debate is what you're looking for.
One, fairly certain, way to, "cut down on misunderstanding, arguments, and "rehashing" is to deftly replace the question mark at the end of your answer with a period, and simply move on. I wouldn't think ANY official would provide an irrational answer to any question, although if the person asking the question shows no interest in understanding or accepting the answer, it's probably best, for both parties to make the exchange as brief as possible.
