Even when so many people post insults and upvote them, that still doesn't exclude it from being a (very) loud minority. I'm sure there's plenty of people who don't stand for that, but don't know what to say either. It isn't easy to call people out for their behaviour either, and there's no downvote button either to show disagreement with those insults. I've had people gang up on me randomly on Reddit, so I know how disheartening it can be. I feel like it's inherited from Reddit, in part because the voting system invites it, and in part as a tendency present in its userbase. Probably the majority of this site's userbase comes from Reddit after all. Anyway, I do think this should be addressed, considering that the pyramid of debate promises a better experience.
