thats not true the japanese have the highest iq's and so do the chinese in the world and rarely do they intermarry.Biodiversity is bs there no proof of its truth

Well, I have to agree, though the fact that Japanese and Chinese do not intermarry(not even among eachother) is no real support for their high IQ's(which I think is disputable).
However, this does not suggest that I am for intermarriages, I do as a matter of fact, think that in today's world, intermarriages are a fine way to destroy cultures, by corrupting the identity of an offspring.
And to be honest, more genetical diversity does not equal better offspring.

But in countries like America, where people don't possess real identities beyond their skin color, sure. Let them have their mulattos in abundance, hell if I care.

japan is an isolated island nation what else could possible explain it and yeah the chinese and japanese hate each other. Japan has only recently become open to the rest of the world
