Not exactly a new concept...
I can appreciate Powell's point on integration. They (immigrants to Britain) don't integrate...they immigrate alright, but the majority don't even try to integrate.
As a child of forced "integration" in the south, for me,
the experience was more akin to the destruction of the middle class white culture in our community...having little to do with the intended purposes of integration...as
in Powell's concept, most of those folks then weren't interested in integrating either, most were more interested in running the whites out...and eventually they were successful.
Some may attempt to label me a racist for relating my childhood experience in forced multi culturalism. I was a child and held no prejudice...and was taught no prejudice.
All I remember is the hurt on my grandfather's face as we said goodbye to the homeplace he had dedicated his life's blood and sweat. He died longing for that place in his heart.
