Take a step through the looking-glass to a strange land, one where white people buy self-help books to help them cope with their whiteness. Perhaps you know it. All the inhabitants seem to be afflicted by serious delusions, for example that racism doesn't exist and if it does it can be cured with a one-hour inclusion seminar, and bizarre collective hallucinations, like the widely held idea that Britain's only role in slavery was to abolish it. But there is a serious side too. Society cannot face up to the racism at its heart and in its history, so the delusions, irrationalities and hallucinations it conjures up to avoid doing so can only best be described as a psychosis, with the costs being borne by the sons and daughters of that racist history. Living in a racist world is like living in a world that bears no resemblance to reality.
