Actually, segregated communities were created by intentional policies implemented by whites.  Your theory, while creative, doesn't reflect reality.

That's incorrect. People self segregate because humans naturally prefer, for the most part, to be around their own kind. Blacks are very touchy feely with each other and call each other brother because they like each others company more than anyone else's and that's ok. White people like peace and quiet which is why you have white flight. Indians and chinese keep themselves to themselves to the extent that one doesn't even notice they're there.

In 1933, faced with a housing shortage, the federal government began a program explicitly designed to increase — and segregate — America's housing stock. Author Richard Rothstein says the housing programs begun under the New Deal were tantamount to a "state-sponsored system of segregation."

The government's efforts were "primarily designed to provide housing to white, middle-class, lower-middle-class families," he says. African-Americans and other people of color were left out of the new suburban communities — and pushed instead into urban housing projects.

Rothstein's new book, The Color of Law, examines the local, state and federal housing policies that mandated segregation. He notes that the Federal Housing Administration, which was established in 1934, furthered the segregation efforts by refusing to insure mortgages in and near African-American neighborhoods — a policy known as "redlining." At the same time, the FHA was subsidizing builders who were mass-producing entire subdivisions for whites — with the requirement that none of the homes be sold to African-Americans.

In the United Kingdom, racial segregation occurred in pubs, workplaces, shops and other commercial premises, which operated a colour bar where non-white customers were banned from using certain rooms and facilities.[1] Segregation also operated in the 20th century in certain professions,[2] in housing[3] and at Buckingham Palace.[4] There were no British laws requiring racial segregation, but until 1965, there were no laws prohibiting racial segregation either.[5]

The colour bar, according to author Sathnam Sanghera, was an import from the British Empire, where people living under British rule would be segregated depending on their race and colour.[6]

The colour bar in pubs was deemed illegal by the Race Relations Act 1965, but other institutions such as members' clubs could still bar people because of their race until a few years later. Some resisted the law such as in the Dartmouth Arms in Forest Hill or the George in Lambeth which still refused to serve non-white people on the grounds of colour.[7][8]
