I saw nothing wrong with Chompers reply. In fact it was quite informative. His reply was stating that if you use multiple terms to describe the same thing then you may confuse your audience and yourself in the process. The helpful advice didn't seem to be any sort of attack in my mind. Had paused to consider who was responding to you, you might have re-thought your reply as he was about the only person left that had any desire whatsoever to deal with you.
