I think I’ve settled on the latter. Disagreement is maybe best communicated by the absence of an upvote? And downvotes work best when they signal something that is just off base, and while not reportable, is not appreciated at a broad cultural level.
Taste my righteous wrath and because I can do it with one click without explaining why means I don’t need to and the internet is on my side. Feels like the implicit meaning when I’m downvoted.
