Race as a visual technology

This was a question for one of my 5000 words essay which i have to hand in soon (tomorrow in fact.. hmmm). Apparently, one cannot get away from this subject, huh? I chose that because I wanted to talk about Marxism and capitalism and so on and so on. However....... all the readings I do kind of point back towards that line of thinking. Now, I am trying to start D&G's chapter on faciality in their book "A Thousand Plateaus: Capitalism and Schizophrenia". I wish I could write like them. *sigh*..
