The National Review has fired its contributing editor John Derbyshire after he wrote an article for a website urging white and Asian parents to tell their children to avoid black people.
The National Review's editor, Rich Lowry, called the article "nasty and indefensible" while defending Derbyshire himself as "deeply literate, funny and incisive".
He wrote in a statement about the article on the National Review website: "We never would have published it, but the main reason that people noticed it is that it is by a National Review writer.
"Derb is effectively using our name to get more oxygen for views with which we'd never associate ourselves otherwise. So there has to be a parting of the ways."
British-born Derbyshire wrote the article for Taki's Magazine, run by the rightwing Greek socialite Taki Theodoracopulos.
He suggested white and Asian parents should give their children a "talk" urging them not to attend events where black Americans might be present in large numbers, to avoid black neighbourhoods and not to be a "good Samaritan" to black people who appear in distress.
Derbyshire wrote: "If accosted by a strange black in the street, smile and say something polite but keep moving."
He added: "If you are white or Asian and have kids, you owe it to them to give them some version of the talk. It will save them a lot of time and trouble spent figuring things out for themselves. It may save their lives."
The piece, a response to articles written in the wake of the Trayvon Martin case about "the talk" that black parents give their children on how to survive racism in America, sparked fury. Many Twitter users sent messages to the National Review asking them to condemn it.
