Ta-Nehisis Coates quotes John Derbyshire:
I am a homophobe, though a mild and tolerant one, and a racist, though an even more mild and tolerant one.
Coates seems to think this establishes something about how unsavoury a character Derbyshire is, but what it really shows is that Derbyshire is a reflective and honest person. Because anyone who claims to be entirely free of prejudice is stupid or dishonest or both.
