I've actually done this, because most immediately important stories bubble up to the top, even though this isn't a site strictly for world news or politics.
Anything related to race and most news that could be construed as political gets flagged off the front page no matter how important it is or how many up votes it gets. You need to be constantly browsing or hope dang is browsing and decides to actually save an article against people using the flag button against the rules of the site to ever see any such news if this is your main news source.
I’m glad those incendiary articles are kept off of the main page, because they are available everywhere else on the Internet.
Allowing them here would likely have a negative snowball effect.
Sure, but GP said "most immediately important stories bubble up to the top".
Trasmatta said important stories.
I didn't say I never read any other news source. I just try to avoid them on a daily basis because they're almost never actionable, and just make me depressed and unable to function. If there's something that's immediately actionable, then I find it will generally bubble up somewhere like Hacker News.
