Posting like this will get you banned on HN, regardless of how wrong someone else is. You may not owe that person better, but you owe the rest of us much, much better, if you want to keep commenting here.

I'm going to put this down as an isolated lapse, but please take the spirit of this site to heart and don't do this again.
