There's really one thing missing from the guidelines IMO - "don't downvote for disagreement, downvote for offtopic/flamebait/inappropriate comment".
Well, this should be obvious, but it sadly isn't...

There was a time when downvoting someone was accompanied by an explanation of why the downvote had just happened, but I think that didn't live long.
Either way, after the divisive last few years I don't think that that many people care for downvotes anymore, i.e. for what "the other side" thinks.

Maybe you're talking about some other site, but I don't remember HN ever operating this way. Downvoting disagreement is one of the oldest norms on the site.
