The comment is flagkilled now. These things take time; there's no way around that.
Literally everyone with strong ideological passions feel that HN is "overrun with garbage" and they all have contradictory definitions of "garbage" - basically whatever they strongly disagree with. This kind of feeling is a mirror of your own passions (I don't mean you personally, but everyone who feels this way, with all their conflicting points of view). It is not a reliable compass for moderating a large international community.
To put it crudely, ideologically passionate people want us to promote what they agree with and ban what they disagree with. That's no basis for moderating a diverse community, and it would be crazy-making to try—one would be walking into a hornet's nest of contradictory demands (because on what basis would we conform to one demand rather than another?), and the demands would only get stronger with every attempt to satisfy them. I don't think this is a good path.
There's nothing specific that you've brought up that isn't addressable by the way we moderate HN today. The fact that we don't see everything and that it takes time to moderate flagged comments are just practical realities of running the site. Demanding that we see and take care of everything instantly is unrealistic.
