Of course it’s just my view, I don’t know what people are actually doing. But I’ve seen comments that I thought were good discussions of the topic at hand downvoted for describing the other side of an issue, even if the commenter doesn’t agree with it. To me the only reasons to downvote are things like trolls, off topic, personal attacks, racism, homophonic, and the like.
@limelight79 that does sound like vote-to-disagree. I’m with you there, I don’t like it. Downvotes should be reserved for things that don’t contribute, like trolling and racism etc.
I also think it’s incredibly rude if two people are having an amicable discussion and one downvotes the other one. It’s like trying to punish them.
On kbin, votes are not anonymous, which has had the effect of making people downvote more sparingly. (Also, although we don’t federate downvotes from other instances so we can only see downvotes from kbiners, it also means our downvotes on other instances are pointless).
