It depends on how you define the word "racialist." If you mean being conscious of the differences between men and nations, and from that, races, then we are all racialists. However, if you mean a man who despises a human being because he belongs to another race, or a man who believes that one race is inherently superior to another, then the answer is emphatically "No."
When asked by David Frost if he was a racialist (3 January 1969), from Simon Heffer, Like the Roman. The Life of Enoch Powell (Phoenix, 1999), p. 504.
