Using the name Football(soccer) would imply that the major name is football and that soccer is a minor, less important name. Trouble with that is that it's not the case for at least half the population of Australia. I am more and more convinced that those pushing the name football here have virtually never spent time on the Aussie Rules side of the Barassi Line, and so have absolutely no idea what they're talking about. They are arguing for what they want things to be, rather than what they are.
