This can also go the same way for upvotes. If you have to put some thought into a disagreement you should do the same for agreement. So upvotes should be removed too so the platform just operates on voiced agreement or disagreement in the comments.

well, even if we wanted to do this we couldn't--it's not toggleable on our end. but if you want to get a simulacrum of this experience i believe that's essentially what turning off scores does, which you can do in your user settings.
