It's not a popular opinion. But this conspiracy theory stuff is just a total endless circle. There so many variables that go into winning a game and you want to focus on one and bang on about it endlessly. Get over it. West Coast have been a good team for a long time, so was Hawthorn - they get more frees because they are better at Football. If your team wants more frees they need to get better at that. With umpires we have a stupid confirmation bias - I personally hate sitting in the members area for Collingwood games because literally with the first free against us people start foaming rabidly - surely there is no other sport in the world 50% of the supporters energy goes into screaming about umpires and then moaning about endlessly afterwards.
No, that's pretty much most fans in most sports.
