Sorry if this is the wrong place to have this discussion, but I don't quite know where I should put this. I posted an answer to a question yesterday Minimum operating temperature - Outer Space? and I noticed when someone else added an answer which I responded to saying I felt it was not answering the question asked.

I don't feel that the expanded response is on topic, and the user is now posting comments which contain misinformation on my answer or that address comments posted to his answer. I feel like posting responses which address his comments are only going to exacerbate the problem. What is the appropriate response to "this is on topic but incorrect!" repeatedly?

Thanks for any help.
