All nations have national narratives which are, at best, partial and, at worst, hallucinatory. They are always clichés. The old canard that the Brits were "tolerant, fair-minded, self-sacrificing and incorruptible" has simply been replaced by a new one to which Leith vigorously and unquestioningly subscribes. British Teeth colludes in the fundamental simplification that we have become vicious dullards and crap at everything to boot. "Nobody believes you at first," says Leith. What nonsense. We Brits are all too ready to believe it.
