Yeti, please. People are alleging a conspiracy all the time. The 'AFL wants a Victorian Grand Final', 'they look after Sydney' etc. Even your allegations of known, unaddressed incompetence and conflicts borders on conspiratorial.
I have no argument with free kick counts and inconsistent decisions being considered evidence of bias, but it's being presented as strong evidence, when it is actually really weak. Inconsistent decisions are are more likely a product of it being a really difficult game to umpire, poor sight lines, etc. How often have you gone nuts about a decision, then seen another angle and realised it was actually a good call? Or gone crook at a game, seen the reply and gone 'oh, so that what it's for'.
As for the conflicts, I can't speak to the Margetts one - I don't know the backstory. But again, you are presenting things as fact when in fact they are mere speculation. Do we know Fischer hates Roly, and wants to see Freo do poorly? You've assumed there is some link between perceived free kick counts and his relationship with Roly (revenge motivation), but that is wild speculation. Most people who are coached by Roly speak well of him. Have you heard Fisher speak otherwise? But that's two out of 30 umpires.
Richmond got a pretty good rub of the green statistically, but will remember this season for one free kick that wasn't paid. Like i said, anecdotal examples of bad decisions are close to meaningless. You'd be a smart enough man to understand confirmation bias. If footy umpiring wasn't a perfect storm for that, I don't know what is.
And ROTV, yes, I do understand unconscious bias, but to have an negative influence on a systemic level that bias would have to be shared. There's no real basis for most umpires to share that view of Freo. In fact, most of those based outside of WA would never really consider us at all. It could explain individual cases though. Dalgleish comes to mind.
A place like Dockerland is a great place to come and vent about umpires and make unfounded allegations of bias. It's all part of the fun, and perhaps it's uncharitable of me to argue otherwise. I know I'm not going to change anyone's mind, I think it's important for people to know that not everyone shares their view about it. Because you know when you hear a fan of another team complaining about umpires how you roll your eyes, there's a reason for that. It's because deep down you know they're talking nonsense.
