The irony I saw is that I was responding to a point made by kansface, rebutting a misconception that really isn't true. In doing so, I provided evidence to that, pulling in quotes and citing my methods. I created content. Yes, it's not a prize essay, but it took some minor effort, and more importantly it added information to the conversation. It also wasn't derogatory - I didn't imply kansface was a fool, I only discussed the misconception itself.
Then, despite your earlier protestations of people tearing down instead of creating, you just dismissed what I did out of hand with a mere "we're not talking about that". You added nothing to the conversation with that comment, and tried to stifle a conversation branch in process.
While the greater conversation is about more than HN, a specific point on HN was made, and the same specific point was rebutted. Cutting off that conversation is doing exactly what you were complaining about originally.
