Yeah, I have to admit that I felt a kind of 'not following the letter of the rules' when I used the word 'cute'. Frankly, the argument against 'snark' on HN is a bit wearying to follow 100%. All I would have to do is obfuscate a bit and it sounds like principled disagreement ("It's perhaps a naive take that you ...", "I don't completely understand the line of reasoning that led you to think ...").
The thing is, out there in the world, you don't have to bother worrying that there's some starchy HN exceptionalism that doesn't allow you to answer something that's complete bullshit with a 'proper intellectual response'. It is a bit wearying to constantly deal with juvenelia ("Getting dropped from network TV is like being 'disappeared' by Stalin) in a fashion that would be commensurate with, say, a improper attribution of a remark from Wittgenstein uttered in the drawing room.
It feels like HN's policies against 'snark' have the (no doubt unintentional) effect of shifting the Overton window towards requiring remarks - no matter how juvenile and daft - to be met with proper and careful drawing-room etiquette. So saying stuff that's completely absurd needs to be either unanswered (and left to stink up the room) or carefully argued against (making it sound way more plausible than it is).
I understand that the slippery-slope version of my argument here suggests that anyone can meet anyone else with a torrent of personal abuse simply as a result of disagreement. That being said, I'm not 100% convinced that the right answer to someone uttering absurdities is to meet them with logical, guideline-approved non-snark.
Also: to the nice people on the subthread defending my remark as somehow not snarky, thanks, but no. I intended to be a prick here - there's no entirely guidelines-compliant interpretation of my comment. My argument above is that judicious snark is probably better, and more honest, than either masking it ("your argument is characteristic of arguments made by people no doubt considerably less intelligent than you obviously are, my fine Sir") or by pretending that absurdity isn't absurd ("Well, you see, Stalin actually made people disappear and systematically erased them from libraries, while in this case, what we're talking about is...").
