I think maybe that's exactly how people are using it, it's just that most people aren't thinking "oh, well, this post made me a little mad or uncomfy, but I like the content and discussion that it's spurned, so I'll toss it an upvote". I think most people are more inclined to go "THIS POST MADE ME MAD! GRUG DOWNVOTE!". It doesn't even really not make sense, it would be kind of insane to spend like, even just a minute, thinking consciously about every single upvote or downvote you make, it would take a million years for anyone to ever upvote or downvote anything, and a lot of people would just not engage unless they were really committed, which doesn't necessarily map to their level of discernment, but might just instead map to how mad people could get over a given thing. Plenty of people could get mad enough about a thing to sit through a minute long wait period to downvote something.
