I think you might be confusing supporting MO with referees often trying to understand why mistakes might have been made. This is, after all, a refereeing forum. It was the "awful performance" that had my concerns raised, not many people other than Liverpool fans think it was anything even close to that. He potentially fell victim to simulation, but this wasn't a KMD as you described it, it was a foul in the middle of the pitch that Liverpool then failed to defend properly. And he might have missed a foul in the build up to the equaliser, I personally don't think it was as it was consistent with contact that he had let go throughout the game.Conversely, perhaps tell people who haven't even watched a game to stop opining as if they have? I might be a Liverpool fan, but I'm also a ref (who understands the concepts of "dives" and "foul tolerance") and I'm someone who actually watched the game. I don't need someone who didn't see the game looking at isolated key incidents and trying to tell me MO was "adjusting his tolerance" when it's blatantly obvious he just missed dives and got foul detection consistently wrong, including in moments that turned out to be pivotal.
I find myself being told I'm wrong by people who didn't watch the game and are supporting MO based purely on the fact he wears (metaphorical) black. Referees are the people who came up with the idea that there are three teams on the pitch - I will take your note on board, but maybe keep a critical eye out for people who blindly support the third team with blinkers on as well?
And I have dealt with people that didn't post appropriately, one of which is currently on holiday. I'll be open and honest, I was 50/50 whether to issue the same warning for your post but went for an admonishment instead.
