I realize that as social and political conditions become more polarized, it gets harder to practice the intended spirit of the site, but if HN is to survive, we all have to pitch in. That's one reason the guidelines say "Comments should get more thoughtful and substantive, not less, as a topic gets more divisive." "More divisive" is the trend of the world these days, and there's no way HN can expect to be immune from that.
Being that the parent comment is dead I'd assume that this comment won't be publicly visible but I'd like to give a deeper commentary that could be misconstrued by some here, as well take some thought to put together so I'll send that to your HN email.
Regardless of the above, I'm chagrinned and remorseful to generate non-positive dialog here.
