No one has ever argued the referees are infallible: that's why they introduced the bunker and appeals. Which sometimes reveal refereeing errors, and sometimes the players getting it wrong. So it goes, we're all human. We make mistakes.
Anyone who's ever refereed can tell you who difficult it is being the man in the middle. Forward passes are much easier. The touchies are invariably right there. Unlike the fans, especially those watching TV, who are almost always wrong on borderline forward passes. Regardless, it's pointless arguing with them. And crass to call them cheats.
But to go further and insist there's a criminal conspiracy to rig games, I won't entertain that. And it seems like it should be beneath you as well. You're not a yobbo.
In this competition, in any competition, all contestants agree to abide by the referee's decision, knowing sometimes they'll get things wrong. When you have to make up conspiracies that the referees are cheating in order to support your team, you're failing the spirit of the game and ruining it for those of us who respect the core agreement.
I deplore this shit.
