Dad's Dream-
Let me help you with this. The poster was not assuming you were selling anything. He was using figurative language, a metaphor, I think. This may clear it up:
I think what he meant was, you are offering an opinion, but he thinks you know in your heart it defies common sense, so you use the tactic of mincing words.
I don't think anyone else on the board thought you were actually "selling" something, but thanks for the clarification anyway.
But this kind of parsing of words makes your point of view all the more suspect.
