The idea of forum moderation is that when enough people complain, regardless of who is "right", you do what's necessary to stop any future problems. I don't need to go through the litany of flame wars this guy has induced, a search on his username will tell you all you need to know. There is a clear pattern of trolling without any sincere interest in debating the substance of the issues.

In this instance, I tried to find a balance between getting a good message out and avoiding a scene. In retrospect, it was silly of me to think that would happen, and I should have deleted it altogether. I'll do that next time.
