Even if just about everyone does it: "White flight", anyone?
"A conservative writer in US has come under fire for urging white and Asian parents to shield their children from contact with black Americans they don't know.
John Derbyshire, a columnist for one of US's most influential magazines, the National Review, wrote a piece outlining the "talk" all non-black parents should have with their kids in response to a number of articles offering black parents advice on how to discuss with their children the shooting of black teenager Trayvon Martin.
Derbyshire advises white and Asian parents to keep their kids from black neighbourhoods and events where there a lot of black people present and avoid living in areas run by black politicians. He even suggests they should tell their children to avoid helping black people in distress.
"If accosted by a strange black in the street, smile and say something polite but keep moving ... 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," he writes in the right-wing Taki's Magazine.
The piece triggered a furious reaction in the US, with many attacking it as a "disgusting rant" and calling on the National Review to fire Derbyshire.
With violent crime by blacks at 9 times white levels this advice is realism, not racism. When black crime declines to white levels, then such advice will not be needed. My son's best friend has a small amount of African ancestry but I have warned him to avoid Africans wherever possible out of safety concerns.
But National Review has now bowed down to political correctness and fired Derbyshire. Telling the truth can be toxic in America today.
