That is part of why downvotes exist. They also exist for personal attacks, off topic tangents, posts that don't make sense, trolling, advertisements, AI generated content, and other such things we don't want to see here.
But "downvote for disagreement" is a legitimate use. I personally tried to tell someone that it wasn't, and I got corrected by dang.

This made me realize it's a waste of one's time to write thoughtful, informative, educational posts only to have them buried and downvoted by man-children.
If we go by empirical evidence alone, it's a more effective use of time making Reddit-quality quips.
Depends. Do you want points, or do you want to say what you have to say?
And, there have been times when I have upvoted something I disagreed with, because it made me think.
if you are writing things to get blessed by votes, your incentive might be in the wrong place to begin with.
As an example, my point that it is fine to downvote for disagreement got a few downvotes. Ironic, no?
