There's some part of my brain that applies display:none to the upvote/downvote function on every platform.

So if I don't vote on your content it's not because I hate it. My brain is just wired to automatically edit out anything that's not content. Mostly this means ads, but voting features seem to have been caught in the net too.

I think of it like a digital facial expression. Upvoting is akin to smiling or conveying some other positive emotion like affirmation or understanding (even if the subject matter is inherently negative). Downvote is the opposite- someone says something irl that makes you frown or grimmace, or you know they're telling you a lie, your expression can convey that without a single word. Here, downvote.

There's no real etiquette - if you feel like you want to give an up or down vote, just do it and don't put too much thought into it.

I generally don't downvote unless somone is being bigoted or hateful.

The latter. If it's just disagreement a quick reply is best, and sometimes it gets worked out just fine.
