That problem with Reddit also applies to HN and every other "moderated with a light hand" discussion forums today. Don't go to Hacker News to speak positively about 'System Integrity Protection' or 'Sealed System Volume' on Apple computers, or to consider how the GPL might be harming open source, for example. The comments will be a tire fire of people repeating the same handful of hostile viewpoints as top-level threads (rather than upvoting that which they agree with), drowning out rational discussion and driving away anyone who doesn't agree with their viewpoint. The conversational warfare tactics are exactly the same as those used on Reddits about anime, video games, and all other topic people feel strongly enough about to create a forum for and allow participation of this nature.
