Perhaps the best-known quote from Martin Luther King Jr. is: “I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.” The kind of society that King dreams of in this sentence is often called “colour-blind” – in a meaning referring not literally to the disability, but to skin colour being irrelevant to people’s lives and the way society judges them. Prince Ea’s wonderful “I am not black, you are not white” video, which I cited as an exemplar of qualitative individualism, further expresses the ideal of colour-blindness: race is just a label that diminishes who we really are. For my own qualitative individualist reasons, it is an ideal I endorse.

In recent years, though, the concept of racial colour-blindness has come under attack. And I do believe that one strand of this attack is entirely justified.
