Bloody hell, the horseshoe theory's alive and well I see. Well that or you've been hanging out with Ross May...
I'd happily say to Paulo and Taumalolo's faces that they're about as Samoan and Tongan respectively as Anthony Albanese is Italian or Shane Warne was a German. They were both born in NZ, raised in NZ and Australia respectively, went through school in NZ and AUS respectively, learnt the cultural norms of NZ and AUS respectively, learnt their sport and profession in NZ and AUS respectively, etc, etc, and no amount of soft bigotry of low expectations or blood and soil BS can change that.
Had they been born and raised in Samoa and Tonga their lives would have turned out completely differently, to the point that they'd effectively be completely different people in most respects. It's highly unlikely that they would have ever become professional RL players as a singular example.
The only reason that you're daring to suggest that they aren't Kiwis/Australian in this case, where you'd happily accept that both Albo, Warne, or the rest of roughly 50% of people in our country whom were either born overseas themselves or have at least one parent born overseas (god knows what the % would be with at least one grandparent), are Australians, is because of their race. In other words they don't present as the stereotype of an Australian (or Kiwi as the case may be) that you have in your head, where as Albo, Warney, etc, do, and I find that extremely f**king gross frankly.
But let's not allow your, interesting, ideas about race and ethnicity distract from the fact that your holding international RL to much lower standard than you hold international RU, and that that is blatant hypocrisy.
