I don't believe that moving toward more segregation rather than less is in any way "forward." I fact, you might call me a Pollyanna, but I believe things are getting better rather than worse in this area.

I think it's just a fact of life that a very strong and well-defined Afrian-American culture exists in the US, and that no comparable separate culture exists in the the UK, at least not for nearly so many years.

I suppose it's arguable that the large numbers of black folks that have moved to Britain from the Caribbean and elsewhere since WWII may have achieved enough "critical mass" by now to have begun developing an independent culture. But it's not nearly so "time-honored" as the American black world, and it'll never be as severely separated from the mainstream culture as was the American black world for centuries.
