I know the internet (including HN) supplies endless frustration, but just because of that, we all need to cultivate the skill of not responding from a triggered place. Comments like the GP and https://news.ycombinator.com/item?id=29525651 definitely just make things worse.
Put another way: users here need to follow the rules (https://news.ycombinator.com/newsguidelines.html) regardless of what other people are doing. It always feels like the others both (a) started it, and (b) are doing worse—that's just baked in to human perception—so we can't use that as a basis for commenting. If we do, a downward spiral is the guaranteed result (https://hn.algolia.com/?query=downward%20spiral%20by:dang&da...).
