on somewhat of a crusade against downvotes
It’s true. For me, to downvote an opinion (and this is what the vast majority of downvoting is) is the virtual equivalent of slapping someone in the face, or telling them to shut up. We don’t do it in person, we shouldn’t do it virtually.


Egregious straw man, obviously I don’t think that.
Says who? You? What if it were you “misunderstanding” this? I know your version is the majority one, but there are plenty of people who agree with me that downvoting is toxic, hence the existence of downvote-free instances.
The big difference, to bore you with what you must already know, is that a downvote affects in most default configs the visibility of the comment. So it’s effectively a mild form of censorship, which IMO is not “softer” than a negative reply. And it’s certainly not better than than a constructive negative reply, which, believe it or not, is possible to do.
The best argument I have seen for your case is that downvoting provides an off-ramp for potentially sterile conflict. I.e. people hit the downvote button instead of replying with rage. That’s a decent pragmatic argument. But whatever reason I personally manage to control my rage at other people’s “wrong” opinions, so I don’t think it’s too much to ask them to do the same.
