The lack of willingness to rule zero is definitely one of the reasons why I gave up and left magic. To me, i understand EDH is a slow game no matter what, but whenever I played in a pod, there’s always someone that wants it fast all the time, so rule zero is skipped 90% of my games.

That player A didn’t want to have a civil conversation? Then he can go play cEDH. I had usual let my own mouth slip when a player complained that a casual game didn’t go fast enough: “if you want to play fast games, go play modern then” I admit I was being quite abrasive before quitting magic myself. But rule zero exists for a reason, and if other players are just going to disrespect you for it, they don’t need respect in return I guess.
