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.
I see downvoting of comments for stuff that does not require mods, but is still people being assholes or something not belonging. I don’t vote enough on submissions to have an opinion there :D
