Mitchell I think you'll find that if you look closely enough and the 
genetics and intelligence issue you'll find that, not only is there no such 
thing as race,  there is no such thing as genetic differences in 
intelligence full stop. Intelligence itself is an ideological construct 
rather like money. Like money some people have more of it than others and 
like money it can be inherited. It appears as an ideology in the latter part 
of the 19th century when all the property was bought up so to speak and the 
professional middle class, Hobsbawm's  nouvelle couche sociale,  needed a 
justification for privilege. So you had Francis Amasa Walker president of 
MIT teaching his students about the rent of (their) ability, their property 
was their ability and in Britain you had George Bernard Shaw writing about 
socialism as the "paradise for the able".
