Oh this is nice. Simple points of order concerning HN operation are downvoted now? (Hint for drive-by downvoters: if you don't know what we're talking about, you probably have "showdead" set to "no".)
Open the page in an incognito tab, so HN won't know who you are. (or log out if you prefer) I expect that your original comment will no longer be visible. This appears to be similar to the hellban functionality, in that it's hiding from you the fact of flagging this one comment. Although I have no problem with the use of hellbanning, I don't see how the behavior we see here, with respect to a mildly sarcastic response to more strident sarcasm in TFA, could be considered a good thing. Hmm, maybe I'll write a Chrome extension to remove this misfeature.
