" There has always been racism. But it developed as a leading principle of thought and perception in the context of colonialism. That’s understandable. When you have your boot on someone’s neck, you have to justify it. The justification has to be their depravity. It’s very striking to see this in the case of people who aren’t very different from one another. Take a look at the British conquest of Ireland, the earliest of the Western colonial conquests. It was described in the same terms as the conquest of Africa. The Irish were a different race. They weren’t human. They weren’t like us. We had to crush and destroy them. "
