It's really a comment-by-comment thing rather than a people thing. If you're seeing cases where we're failing to moderate a post that cries out for it, the likeliest explanation is that we didn't see it. We'd appreciate links, because we can't come close to seeing everything here. Or of course you can flag the comment (described at https://news.ycombinator.com/newsfaq.html). In egregious cases, emailing hn@ycombinator.com is best because then we're guaranteed to see it sooner.

Really, are you sure? Can you point to the comment that demonstrates this? Because either I missed something obvious or you're reading perhaps a bit too much into what was posted. Intent is notoriously difficult to read accurately in these posts, as I'm sure you know.
