Wrong. Being played in only Australia has made the sport untouched by outside influence & anglo centric. Those with different cultural backgrounds struggle for acceptance. The forcing out of a player in Adam Goodes is unprecedented in modern sport & could only happen in this insular environment.I am not an RL troll but let's be fair here, while plenty of supporters didn't boo him for racist reasons, plenty of them did. There are a hell of a lot of people in this country who just can't stand seeing a black man be vocal about their treatment and demand change, because those people feel threatened or attacked by it.
This isn't specific to Aussie Rules of course, it's just as prevalent in RL as has been pointed out earlier with the response by fans to Walker and Addo Carr refusing to sing the anthem, among other examples. It's a national issue.
