Proof niggers are dumb (IQ, brain size etc)

Oriental populations in East Asia and North America typically have mean IQs falling between 101 to 111. White populations in Europe, South Africa, Australasia, and North America have mean IQs of from 85 to 115, with an overall mean of 100. Black populations living south of the Sahara, in the Caribbean, in Britain, and in North America, average IQs of from 70 to 90.

Especially contentious was Lynn's calculation of a mean IQ of only 70 for Black Africans living south of the Sahara. Many reviewers have expressed skepticism about such a low IQ, holding it impossible that, by European standards, 50 percent of Black Africa is 'mentally retarded'. But a mean African IQ of 70 has been confirmed in three studies since Lynn's review, each of which used Raven's Progressive Matrices, a test regarded as an excellent measure of the non-verbal component of general intelligence and one not bound by culturally specific information.

Ok, but lets assume you own a farm, you have one pen where you raise white bulls who are known for their low aggresion levels, nonviolence and peaceful nature, sure everyonce in a while you get a bad bull, but in general they are good.

Now lets assume someone wants to sell you his collection of black bulls, known for their aggresive attitude, violence and mean temperament, sure not all black bulls are violent, but about 50% are. Would you buy these bulls and put them in the pen with the white bulls knowing that the black bulls would kill loads of white bulls, and lower the standards for the white bulls, the white bulls would stick to their side of the pen in total fear (self segregation) entirely defenseless as the black bulls come up kill and rape them.

No you would not! You would keep them seperated, one pen for the black bulls and one pen for the white bulls.
