Maybe it'll help to break that one down:
> An American problem created in the US
Comment already starts off pointing flameward, but ok, it could go either way.
> In almost any other country,
A grand and shallow generalization, consistent with flamebait, but ok, still not dispositive.
> The incessant fads and hysteria
This swerve into pejorative language, given the frame already set, is definitely starting to look like nationalistic flamebait.
> a society that is totally dysfunctional
Ok, now there's no question about it.
Comments like this, which combine denunciatory rhetoric with a very low information/indignation ratio, are definitely not what Hacker News is for. This was not a borderline call!
Ok, I think you are right.
