Taxi drivers provide a perverse service to the racial conversation when they refuse to pick up black people. Clearly it would be better if they stopped, so that we wouldn’t be left hailing the night air like fools or relying on white friends to sneak one past the censor like supplicants.

On 29 June, 65 children from the Creative Steps summer camp in Philadelphia took a trip to the private suburban Valley Club swimming pool for a dip. The Valley Club knew they were coming and how many there were because the camp had signed a contract and paid $1,950 in advance for weekly visits throughout the summer. But somehow the arrival of the mostly African-American and Latino children was still a shock. As the black and brown kids got into the pool, the white parents pulled their kids out.
