At HN if a single user flags an article there's no discussion to be had?

The thread in question featured an article about women bearing the emotional baggage of toxic masculinity. The author wrote the piece such that it read as a generalization to all men, which is obviously not the case and the author acknowledges this shortly into the piece. Anyway a single person took offense to the contents, presumably without reading the article, flagging the thread and it is locked and condemned to obscurity. Regardless of the validity of this person's reasoning, is his action grounds to deem there's nothing to further to be said about the contents of the article. Seems like a recipe for an echo-chamber, and in an industry notable for a particular hue of pill is this a bug or a feature?
