If post X has a score strictly less than post Y, then it follows that there are either people who upvoted Y and did not upvote X, or people who downvoted X and did not downvote Y. If I think the score of X should be equal to the score of Y, then I am disagreeing with the voting behavior of the persons in those sets, at least one of which (as I said) is nonempty.
