I sometimes post news articles that examine possible problems in society. Some may agree with the author, some may disagree. I often see these posts being downvoted if many disagree with the author.
Why do you downvote the post instead of commenting to express your disagreement?
As far as I understand, the idea is to upvote the post to spur conversation and comment to express your agreement or disagreement. Or did I misunderstand something?
Better question is why are you carrying over the obsession with karma over to lemmy? Are you the type to say before a post “I’ll probably be downvoted for this but…”
Just stop caring about it completely.
