The true destructive mentality is intolerance of others with different preferences for gameplay and different definitions of fun. If you believe that despite the fact everyone is actually playing within the rules that the game is designed with, almost all of them are playing the game wrong and need to be stopped, that is the height of destructive intolerance.
You would rather nobody play the game at all than even a single person be playing it wrong, according to your own personal idiosyncratic “rules games ought to be played by”.
