Although I agree with most of what you're saying, Asians, particularly the Japanese (one of our main trading partners), identify with koalas, kangaroos, phrases like G'Day and other yobo statements like "crikey" and "fair dinkum".
I remember when I visited STh. E. Asia to visit some childhood friends and the first thing i heard when I walked into their house was "G'Day, mate". These people had been born and bred in Asia-so you can't tell me it's just in Europe and the America's.
Anyway, this is a stupid issue. Who cares what people say, honestly? It's called freedom of speech and we shouldn't all be debating it.
