That's an interesting censorship tactic: if you don't like a topic or an idea, start a fight about it, the ruder and unproductive the better. Your disliked topic is thrown out like a baby with the bathwater, an objections to the censorship can be countered with the misdirection that the topic or idea isn't getting suppressed, just "fights."
That's why I think, in the interest of open, good-faith discussion, the flamers themselves need to be moderated, but not the topics that attract them.
You're not wrong, it's an instance of a heckler's veto.
But HN policy is (basically) to allow the veto to work as the lesser of two evils, on the theory that there are lots of other places to discuss this sort of stuff. I think that's a reasonable policy for a tech site.
