You seem to misunderstand most of the issues at hand here. Firstly it is very much a chicken and the egg scenario with respect to coming out and acceptance. There must be a level of acceptance to open the doors for people to be willing to come out but the more people who come out the more accepting society, or it's sub groups become.
Also, as much as 2010 wider society is more accepting than in the past, it isn't a completely accepting society. The wider view in Australia tends to be "it's okay to be gay as long as I don't have to be exposed to it". Eg A gay couple
holding hands still gets looks while a straight couple doesn't. We are hardly living in a society that is fully accepting, and the sport/AFL sub group in society is historically less accepting.
The first openly gay AFL footballer will be put through hell. History teaches us that. It will be an incredibly brave man to do so and every gay footballer after him will have him to thank for their relatively lower struggle. However, to
convey footballers who are not ready to take that bullet of being the first gay footballers as cowards is bullshit.
One of the greatest moments in VFL/AFL history was when Nicky Winmar lifted his top at Victoria Park and pointed to his black skin. Even though it was not a secret, it showed that he was not ashamed of being aboriginal as was not going to put up with the taunts of the racist element at Collingwood.
That ONE moment changed attitudes to aboriginal culture more than any other has and forged a path for many more aborigianl players to join the league and thrive.
Nicky Winmar, like Ian Roberts in the NRL were NOT cowards! Gay AFL players could clear a path in society, the work force and sporting arenas for their gay colleagues but choose not to.
