HN isn't a person—it's a statistical cloud. There is always a spectrum of opinion. Most of the comments here agree with you.
There are some bilious and excessive responses but that's inevitable when a thread is large. We do our best to moderate the site so that they don't dominate.
People commonly overgeneralize-then-anthropomorphize the data points that rub them the wrong way. There are cognitive biases that we all have which make this an easy trap to fall into ([1], [2], [3]), but it's important that we all try to avoid it.
If you (I don't mean you personally, of course, but all of us) allow the negative tail of the spectrum to form your picture of the community, that's bad—because your picture of the community influences how you participate in it and this will cause harmful secondary effects that can, in the worst case, turn into doom loops.
I don't think the primary harmful effects (e.g. bilious comments and upvotes for indignation) of running a large internet forum like HN are avoidable, but I do think the secondary ones are. At least I hope so!
