Blacks and Whites live amongst each other in the UK. It's not like poor Whites and poor Blacks in America that live segregated. In the UK you can have a 20 floor tower block council estate (housing project) with poor White British and Carribean/African kids all growing up together. Living next door to each other. Going to the same school. Playing football outside. The UK is heavily urbanized, so people of all backgrounds are often scattered together. Plus the UK (really England) doesn't have the macabre historical race relations fukkin' up their view of each other with stereotypes and shyt.
It's not all roses but i bet even a lot of the diehard White British nationalists (which usually come from poorer urban areas,) still have a black mate they used to drank with at the pub.
