Hmmm nothing wrong with people wanting to be with their own kind. Many blacks in the 60s and even more prior were not interesting in being with or around white people. They just wanted to have access to the same opportunities as white neighborhoods.
There were many many many majority Africsn American towns as well as major cities that were prosperous prior to integration and after, but poor white people generally did not like that so they would do everything in their power to destroy them... they always succeeded.
