HN is for curious conversation. The idea is: if you have a substantive point to make, make it thoughtfully; if you don't, please don't comment until you do. Specifically, if you can't respect the person you're talking to, do yourself and all of us a favor and don't reply. You'll only make the thread worse, and it's wretched enough already.
If you don't want to see nagging announcements like this at the top of a thread, I sympathize; I don't want to write them either. Unfortunately, if users don't contain themselves, we end up in hell: https://news.ycombinator.com/item?id=22823753. Please contain yourselves.
