As far as I'm aware, the result of the Luton game was free of referee controversy. Luton did get 10 minutes extra time to try and find an equaliser, if you want to play this game.
I don't know why you're upset about fans on a forum being upset about a plethora of really poor refereeing going against us. If any other team in the league had the decisions we've had since Nuno took over, they'd be kicking up a fuss too.
This narrative of a conspiracy theory. It's being overstated. Nobody is really suggesting the PL and PGMOL are meeting in secret rooms wearing cultists robes and plotting the downfall of NFFC.
I think there's a certain amount of sense in saying subconscious bias might be filtering through. Neutrals want the fairytale of Luton surviving, and we're the ones they're chasing, which means neutrals want us to lose games. Referees are just normal blokes who are into their football, and probably would like that same fairytale as everyone else. It doesn't have to be a deliberate thing, but just the benefit of the doubt going against us. Then VAR hasn't been overturning it because it's not clear and obvious enough.
What I do know is the string of terrible decisions that have gone against us is mathematically unlikely to just be rank incompetence - thats a 50/50 split. As I've said before, sit and flip a coin. See how many attempts you have to make to get 8 or 9 heads from 10 coin flips. Hint: it won't be quick.
