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?
I’m not familiar exactly with your posts, but I wouldn’t necessarily assume the downvotes are for the reasons you think they are. Sometimes I’ll downvote a post because I don’t think it’s relevant to the topic or that it’s simply not interesting (and I really do view it merely as a vote, nothing personal). Then the OP will sometimes respond with “I can’t believe I was downvoted because of x, y, z” where x, y, z really had nothing to do with the downvote. If I disagree, I try to upvote because it’s on-topic and reply with my disagreement (which I have just done right now).
