Points vs comments. If there's lots of points on a story but only a few comments, it won't stick around. Or maybe its the other way around? (see below)
There is an automated flame detection mechanism. Don't know how it works. probably some kind of count of downvoting of comments?
Users manually flag.
Most political stories are flame bait; the discussions are low quality.
Most politics is off topic, but if a story has been discussed and this one has for almost a year, posting more about the same story with little change won't add much to the conversation.
E.g. I commented about this story 10 (ten!) months ago: https://news.ycombinator.com/item?id=43212206 and do not feel the need to share my thoughts each and every time the story comes up again, although I did 5 months ago. Maybe in 5 months time I will do so again but not every day!
Users do not want to see the same story permanently on show for discussion - they want novelty.
Users tend to not like: Emotions. Propaganda. Accusations of conspiracy. Less thoughtful and more thought terminating comments.
