It isn't how you or I would do it, but it is a country where all of the black people can fit on a single schoolbus, so the fact that they're addressing race at all is noteworthy. That said, there's also truth to their approach. Race is a construct, and has been understood differently in every society. In America, someone is consider "ethnic" or even "non-white" if they speak Spanish, where in Europe that would be seen as retarded. Race isn't actually about skin tone, that's just how people obsess over it here and now. They did that, it was called True Blood and it ran for 7 seasons.
