Earlier quoted context omitted.
Maybe if the comment added to the conversation somehow it'd be more tolerable. However, all the comment does is insult someone without adding anything interesting. It's a waste of space and time for everyone else reading it. It doesn't belong in HN.
Expressing incredulity and frustration at the obtuseness of someone's complaint doesn't seem especially useless to me. Why is expressing emotional reactions pointless, in your mind? Doing so gives everyone more information about the reactions they might expect to their concerns... it enforces social norms, etc.
The problem is that the comment provides nothing else. You can do the same thing in a more civil and constructive way. Just look at your comments. You are providing logic and rationale for your argument. I don't agree with you, but you're adding to the discussion. Now compare that to "I'm sick of you people. Stop whining about other people's comments you big baby". Someone can correct me, but that doesn't belong here and that rule has been around since the beginning of HN. It's been written and clear along with the reasons why. It's the way things have been done here. If someone doesn't like it, they can post on reddit instead.

"Be civil. Don't say things you wouldn't say face-to-face. Don't be snarky. Comments should get more civil and substantive, not less, as a topic gets more divisive.
When disagreeing, please reply to the argument instead of calling names. 'That is idiotic; 1 + 1 is 2, not 3' can be shortened to '1 + 1 is 2, not 3.'"
