You can tell who did and who did not read this article. In it, sparrows are a metaphor for Koreans and their descendants who were displaced by the Korean War.
Some comments can go either way. I only see one that really looks like they didn't read the article. Top level subtweeting seems like a bit much for that.
It looks like it is too much to ask for some people to read the article before commenting. I wonder why they do this, are they being paid to comment? Are they bots?
the linked site will be of varying quality. often the site's text will not be readable on $platform. complaining about that is gauche though, and the comments will often have something to reply to anyway.
Not to mention, half the time comment section here is much more informative than the original submission itself.
Some submissions are really worth reading. Others are worth more as conversation starters. Of those, some are submitted (and upvoted) intentionally to be the latter.
That and it’s HACKER news. Basic infosec, never assume positive intent. Generally and by in large the site is incredibly well moderated and the current community is largely good about self policing… that said this site has bigger eyes on it than lets on…
