"Then don't read them" is like saying "then don't eat it" if someone objects to garbage with dinner. It's also not practical advice, because it takes energy to distinguish signal from noise, and the more noise there is, the worse the site becomes, making it less worth it to spend that energy.
Believe me, I'd love to be able to reduce every category of low-quality comment on HN. That's not possible, or even close, so we have to pick our battles. The guidelines single out certain classes of comments, like ones about voting and insinuations about astroturfing because those are particularly common and particularly prone to make discussion degenerate. Ditto for ideological battle, shallow dismissals, and so on.
We downweight off-topic complaints about website design being broken, etc., especially when they're sitting at the top of a thread. Ditto for shallow dismissals like "didn't read past". But it would take time and energy that we don't have to post the same sort of moderation replies to all of those. Also, I don't think the community would support it—the threads would likely fill up with many more backlash comments.
I don't recognize most usernames—again, there are far too many for that to be possible. If you're "constantly chided" the reason is that you're constantly breaking the rules. Why not just follow them and use HN as intended? It's not so hard, and since you care about site quality it seems weird to be flouting rules that are specifically intended to protect that.
