I disagree, the downvoting on Reddit is a form of soft censorship. If you do disagree with someone's opinion, argue your point rather than rely on silent protest.
Let’s cut off likes then, cause we can express our opinion in comments, rather than silently like?
I mean, that's not necessarily a bad idea whereby a posts value could be ranked by comments etc. But a like is a basic positive interaction with no downside
How do you not see the downside in a negative thing? Even, aside from the censorship aspect, people will literally dislike being disliked. It's a very basic concept.
