Though I've made my thoughts fairly clear that I don't believe in a shady FA cabal conspiring to make certain outcomes happen, I can understand where the grievance comes from.
FIFA is one of the most corrupt bodies in international sport, it consistently has been found to perpetrate fraud, bribery, money laundering, etc. And at the level of the Football Association there are hundreds of millions if not billions of dollars at play both in title chases, in Champions/Europa hunts for places, and in the relegation/promotion battles. The difference between 1st and 2nd, 4th and 5th, and 6-8th, the difference between 17th and 18th is often times the difference in tens or hundreds of millions of dollars. So it is _that important_ and thousands of people _care_ and play a part in shaping how games are scheduled, officiated, and administered from an operational standpoint.
To be getting it this wrong from an officiating standpoint after instigating video review and making incremental change to the game over the years via byzantine rule change and mealy-mouthed explanations of decisions is not acceptable when your club are on the wrong end of a terrible outcome. If you're a fan of a big club, maybe it has all come out in the wash for you over the years. If decisions have mounted up against you, and you've been in a trophy drought, maybe you don't want to point the fingers at your club and you go looking for a bogeyman elsewhere.
It is comical for Liverpool and Manchester United fans to come on here and be saying "oh you're talking like crazy people" when they are the consistent beneficiaries of the kinds of refereeing decisions that make the average football fan lose their minds week over week.
