America is so large and various that it is not difficult to find extremists there. British documentary makers have lived off them for years.

America’s Hate Preachers (11 October), a film by Hannah Livingston, did not deviate much from the pattern. A couple of self-promoting, so-called preachers were befriended by Livingston and invited to spew out their odious views both in “performance”, as it were, and in private. It was no surprise that there was very little difference; the mask did not slip, and these fire-breathing demagogues never revealed themselves to be tolerant souls in their own homes.

We saw only two “hate preachers”, which is not many from a population of 325 million. They liked to think they were at the head of a movement dedicated to tyrannising gays and Muslims, and they took comfort from the success of Donald Trump, but the evidence suggests that they are becoming less rather than more relevant. Pastor Steven Anderson has one church, the Faithful Word Baptist Church, and lots of YouTube followers. Ruben Israel is a street preacher with a megaphone and a small network of like-minded bigots.
