He saw himself as intelligent because he is white, but unable to flourish because blacks were either getting all the good jobs from a give-away government or they were stealing everything decent white folks earned the hard way. I would be the first to look proudly upon all the accomplishments of Greeks, Romans, Germans, Italians, Norsemen, Celts, etc. But it would be absurd to ignore that all of these peoples were great destroyers of civilizations as well as creators. I can only suppose that our white supremacist feels he is somehow more powerful by identifying himself with a group he declares is superior to all other groups. I am mainly Irish and Italian, but I hardly think I deserve to be proud of the accomplishments of Michaelangelo or W.B. Yeats.
Intelligences always belong to individuals.
They are measured by individual accomplishments, not by group affiliation. It is valuable data, but it is also explosive data because of our racist political history. Such data will inevitably be exploited by white supremacists, twisted for their own political goals and used not to improve racial relations in America but to encourage further racial strife. Such data consists mainly of correlations. And while correlations should convince orthodox empirical scientists of nothing, to the racist researcher, correlations are the heart and soul of their work.
