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.

So do you imply I said that Marx was Black? How did you form that conclusion? You have to let me in on this, it must be the superior leftist logic I keep hearing about. So, we had this going:
What don't you elucidate on how you would like your current beliefs to be politically expressed then?
A distinct lack of Marxism in politics, media and academia.
And all of a sudden!
So, wait. Marx was Black?
It truly must be the superior leftist intellect at work.

In case you did not imply I said that Marx was Black, I require a really good justification for your question. It must be really fun debating like a retard. I think I'm going to try to role-play a Marxist sometime, the typical Marxist appeal to ignorance malarkey looks fun in a debate.
