He asked why you are taking shots at CB like it's some monolith that is hellbent on attacking you. You then say, "Board name checks out." Which insinuates that you think he is an idiot for asking a question.
He is saying (and I paraphrase), "Why are you calling me an idiot instead of answering my question?" Which is a valid question: why ARE you calling him an idiot for asking a question instead of giving a straight answer?
Then your dumb little circular argument took place. I suppose it is difficult to answer a question if you don't know what is or why it is being asked.
