Please don't cross into personal attack when posting to HN. You can make your substantive points without that. https://news.ycombinator.com/newsguidelines.html
Indeed. So let's be consistent "Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something". How did the comment I responded to say anything useful, constructive or usefully critical? Negative but vacuous dismissals like theirs seem ok. I hate that aspect of HN; the nihilism allowed to flower.
(2) shallow as the GP's criticism may have been, your comment was far worse. Responding to a bad comment (or one you feel is bad) by breaking the site guidelines yourself, let alone with a nasty personal attack, is exactly the opposite of what you should be doing here—it's driving the wrong way down a one-way street.
