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.
Lol, point taken. It has to be an actual rebuttal, and I guess that does take time. Downvoting everything you don’t immediately agree with seems like a bad policy, though.
