Healthy discussion.. I suspect it wasn't that though. When someone clicks on an HN link to an article, and chooses to leave a comment on the article rather than discuss it on HN (or as well as) they're probably not posting a nuanced and we'll reasoned point. They're likely just firing some sort of flamebait rubbish rather than participating in a discussion. If that happened every time your site was linked from HN you'd get tired of it very quickly and start to think HN is full of man-children and brogrammers.
