Your prejudices are stopping you taking a fair look at this.
If we ignore the wide player, this is textbook VAR and exactly what it exists for - a game that would have otherwise been decided by an "unfair" goal is 100% what people would have moaned about pre-VAR and is absolutely part of the justification for it's existence.
The players are a full-on disgrace though. They have no idea what he's being sent to the screen for - so what are they arguing about? He's given the most mandatory of mandatory yellows, which happens to be a second, then has been asked to review "something" - these are incredibly standard calls, nothing controversial happens until well after the bench-emptying brawl has already occurred. Awful discipline from these "professionals", it's a shame the actual VAR call is going to overshadow that, because that's the real story here for me.
