The disagree button has always been problematic.
After awhile, it just becomes a quirk of the board.
Seat of the pants observation is that very few disagrees are of a technical nature:
"The Tesla MX lug torque is 60 lbft" should generate a Disagree and a quoted correction.
They are normally fashion related, that is, herd acceptance.
"Does this dress make me look fat?"
"Willy Wonka would make a terrible Secretary of State."
"My Tesla broke down."
etc.
You will note that nobody who disagreed with you dared post a counterpoint.
