I partly agree but would put it differently. When an obscure topic (like ultraviolet blood irradiation) is connected to some trigger in the daily news, people will end up arguing about the daily news rather than delving into the obscure topic. So from an HN point of view, that's the worst time for the topic to appear. HN should be countercyclical instead. This case has made that even clearer to me than it already was.

At the same time, HN is not for internet ragewar and users here should know enough not to feed those flames.
