That’s why it’s a disagreement. I’m not necessarily saying their opinions are factually incorrect, just that they are devoid of empathy, morally reprehensible, and antithetical to the teachings of the religious figure that they are statistically likely to claim to be faithful to. A lack of empathy should not be rewarded.

Typically, the things I disagree with are the things like bad faith arguments, lies, rudeness, or bigoted ideals that purport that not all humans deserve equal rights, etc.

Usually, when I disagree with something, it is because it is incorrect, lying, or particularly mean-spirited. I disagree with people that do not think that every human deserves the same rights. I disagree with people that push for ideologies that would strip other humans of their rights, or that would inflict needless suffering. I don’t downvote people when I disagree with what media they think is good or something. I downvote those that express ideas that are antithetical to what I see as basic human decency or that are factually incorrect.

Personally, I use downvotes to say “I disagree with this and/or it is a stupid/bad/bigoted/etc take, but I do not wish to spend the time and effort to respond and get dragged into a text-based mudfight with someone who is unlikely to speak to me politely, no matter how polite I try to be in my rebuttal.”

I like having a way to say “no, bad, stop that” without having to spend time trying to explain things or engage with someone who I think is beyond convincing anyways.
