I think people feel like they need to do something to try to stop a “bad behavior.”

My guess is that it’s more effective to simply upvote a comment that is getting downvoted “unjustly” in your opinion. At least that’s what I’ve started doing. Even when it isn’t a comment I would normally upvote.

Then there should be a recommendation too that people should write a comment what they don’t like instead of just voting to help people understand what they did wrong. Like this it feels like downvoting is simply abused to push down opinions some don’t like.
