There are a fair few problems and it seems there isn’t much consensus in this thread.
A few points I’ve thought of, I’ve been to many games and there is a fairly large ugly undertone from a vocal minority of fans (I’m a victory fan), I’m not really sure why people think being a douchebag is essential to being a soccer fan.
I think this undercurrent of aggression off the field sets things up to be exclusive for the majority. Also what are these fans so angry about? There are no social or class lines for us to be hating other sides. It screams of people glorifying what they perceive to go in in Europe (where it largely doesn’t anymore).
Then there is the standard of play. I don’t think anyone is expecting it to be up with the top 3-4 leagues in the world, but we should be aiming for a level similar to say the Dutch league. Instead it’s a haven for mediocrity and journeymen who are preferred at basically every turn to youth. This is detrimental to the league and to the Australian national team (though not the only factor, the national team has gotten worse since the a league has existed).
I see your first point, but I've been to City games which don't have the ultra fan element and not only are attendances worse but the atmosphere is dire, same goes for contrast between WSW and Sydney FC (have watched both at home in the past) I'm not sure that argument is all that valid in terms of preventing revenue and growth of the game
Your second point I agree 100% with, there must be better ways to move average blokes (Jade North anyone?) on and encouraging promoting youth.
