I'd say he brought ethnicity into it:
"As an African who comes from one of the poorest countries in the world, a place where a majority of the population lives perpetually in harm's way, you can easily imagine what went through my mind when I heard an evidently well-to-do Englishman say these words with that air of pomposity (if not boredom) that's always the mark of a public school education. But it would be too easy to criticize this film on such terms; it would place me on too high a moral ground. Being something of a gentleman, I would much prefer to take this drama-documentary to task on a more leveled plane, and confront it only as a work of cinema."
Correct me if I'm wrong, but I thought that Yates & Simpson weren't products of a "public" (private) school education.
