@Zerglingman >>White-only inferior to asian/white >In some aspects on balance, I reject that. If we could magically have 3 isolated islands (1 asian, 1 white, 1 mixed), I would guess that the pure race islands would tend to do better than the mixed race island.
also, regarding iq specifically (which is what I assume you're referring to), it's not representative to compare the children of White-asian couples with the average, since Asians who immigrate (and immigrants generally) tend to be smarter than their home countries.
remember than in the US, many non-Whites are classed as whites (some arabs, some meso americans, some mixed race, etc)
