It's not a gaffe. I didn't call it a fallacy because it's not a fallacy. I pointed out that you engaged him in debate and crowned yourself winner, and that I attempted to restart the debate by providing better arguments.
It's interesting, however, that you invented a new context for my words that has no basis in the words themselves, and then used that as your reply instead of engaging on merits.
In fact, I believe there is some Latin name for that particular brand of rhetorical gaffe.
