There are lots of comments in this thread that aren't flagged, so discussion isn't being prevented. It's true that a lot of the earlier comments were flagged, but that was (or should be) because they were flamebait. It's one of the downsides of internet commenting that the flameiest and most reflexive comments appear first in a thread—because those reactions are the quickest to flare up. Better, more reflective comments always take longer [1]. This goes 1000x for a topic like this one, unfortunately.

I've answered that several times in the links I listed; can you take a look and, if there's something specific I haven't addressed, let me know?
(I don't mean to be dismissive—it just takes a surprising amount of time to write those things and I can't do it at the moment.)
I'm pretty sure it's not an easy task to moderate HN. But I'm still surprised by the answer here.
Keep in mind that I was commenting about the situation very early in the thread. My comment applies only to the very first comments that got posted, perhaps the first couple dozen–no later.
Anything that goes against the status quo has a high chance of being flagged, I've seen this happen over and over and especially recently.
