Diarmaid MacCulloch's recent TV prog, on why the English are God's true Chosen People (and it's hard to tell whether his tongue is firmly in his cheek or not), is still available online if you missed it. His theory is that once we accept out innate superiority over all the other peoples of the world, we also bear the burden of a duty to intervene to improve their own ways of life; no foreigner can ever become English, of course, but we permit those in settling here from overseas to be British instead, as a sort of consolation prize, and to copy our way of life.
Now when some Americans sought to publicise the activities of a particularly loathsome African warlord called Kony they attracted a barrage of criticism from Africans themselves, the pressure allegedly driving one of the film makers to wandering around on foot in his underpants in LA. It was the walking rather than than the nudity that alerted police; no sane person ever walks in LA. A flavour of the criticism they attracted as 'White' people daring to lecture black Africans can be found here. It's the usual faux-academic African mix of pomposity and chippiness.
