Yeah, I assume you are referring to someone else doing so, because I was just about to say that some idiot is bound to come in with a racism claim, despite reading all the arguments mentioned previously. I suppose it's racist for Australians to cheer against Philippines too, because cheering against an objectively thuggish team is racist too, right? Ironically, China is one of, if not the, most ethno-nationalist nation in the tournament.
"Oceania is guaranteed a spot between two countries"
I was referring to advantage within a tournament, not to enter a tournament. If talking about entry, what's more difficult, ranking better than Iran+Japan+Korea or ranking better than New Zealand? But, yes, the whole Olympic qualification system is absurd.
Best placings enter Olympics:
1 - Japan (host)
1 - Asia
1 - Oceania
2 - Europe
2 - Americas
1 - Africa
4 - [qualification tournaments]
Europe is initially screwed over, although they should dominate the qualification tournaments.
