Why are you being so touchy about this?
if you bothered to read what I said you will see I wasn't trying to argue anything just point out some things that clearly influence peoples perception of certain teams whether rightly it wrongly but hey you're right so need to discuss it any further. Well done
People will pick and choose what affects them, and in true RL fashion it's usually to pick a negative out. You've mentioned culture, but when the cultures of a few countries appear very similar then it's not exactly a fair comparison.
The majority of players in this WC will be heritage players. It's just the nature of a sport that only has two professional leagues based mainly in two countries. The cultural difference between Italy and Australia highlights the heritage issue more, but it really isn't any different to Samoa and Cook Islands having majority New Zealand-born players.
