IMHO story submissions should be judged based upon their own merits. Toxic commenters can be downvoted/banned but the story submitter shouldn't be punished for the misbehavior of others.

You mean purely based on the expected awfulness of imagined future comments, instead of the actual comments? If so, with a precrime mindset like that, you're fanning the flames of controversy.
There's not enough space on the front page for all the good things we want to read. I'm not interested in expending extra effort to rescue marginal stories with a low likelihood of generating a good conversation. The people most invested in these kinds of stories seem to be almost the least invested in HN's rubric of curious conversation.
I don't call any of the shots around here, but I think I speak for a bunch of different users who flag this way.
I didn't ask you to expend effort in rescuing stories. I took issue with the way you expend effort in burying stories, even before the comment section turns out to go sideways:

Remember though: we're not having this conversation so you can persuade me to change how I use the site. I'm just one doofus here. Wha ye need tae worry about are the t'ousand doofuses standing behind me. (_The Devil's Own_, 1997, starring Brad Pitt and Harrison Ford).
