Maybe those two cultures are the two he can relate to best.In which case it has nothing to do with skin color an everything to do with being comfortable and feeling accepted.And I suspect if he were in a situation. where he had to be with asians and hispanics for an exstended period he get used to it.

Well if that was the case don't you think he would say something like what you just said. Instead he mentioned "worth" maybe he could clarify what he meant. It seems by using the word "worth" he is placing a higher value on Black and Whites over "everyone else" - whoever they are.

Oh I dunno if its true I just gave him the benefit of the doubt. Hes still got a chance to respond with something of equal or lesser value.
