I want to upvote the OP for presenting an interesting discussion but downvote them for being wrong. This presents a case for a non-binary voting option.

A singular like button would still only express one portion of my sentiment. A third option could be many things, none are sufficient: a none or 0 or neutral option is effectively not voting, a sideways arrow or maybe state, or mixed state would express indecision or indeterminism rather than mixed feelings.

Therefore, I propose that a second positive-negative axis is required. The addition of these “sideways” arrows allow expressing 2 kinds of sentiment: towards the post content, and towards the poster themselves. I will not specify whether left or right is positive nor will i clarify which axis (x or y) corresponds to which kind of sentiment. I’m sure this undefined behavior will cause no problems.
