Really, if you don't like it that much and you believe it does not belong here you can flag it. But the best way to make HN into what you feel it should be is to post good links and to visit the new page to upvote the things that you feel do belong here.
We get these comments pretty regularly. Perhaps something could be done to avoid them - like the "Add Comment" page having some basic guidelines. A reminder of etiquette, the things that get downvoted, how to properly object (ie flag)?
It's a worthy sentiment but it's also a useless comment in that people who don't want to read the story should [and will largely have] just step over it whilst those who think it should appear here will read and so will naturally downvote such an objection.
(I up voted it, but it's still grey.)
