On the other hand, downvoting isn&#x27;t really supposed to reflect dislike or disagreement, but rather a comment that is rude, lacks substance or, is otherwise against the guidelines. Unfortunately this rule seems to be pretty universally ignored on HN these days.<p>I&#x27;ll generally re-upvote any reasonable post that I see has been downvoted simply due to expressing a contentious opinion, even if I also happen to disagree.
