How about giving segregationist, such as many of the folks posting in this thread, their own Island somewhere. Raise Atlantis from the ocean. Antiquated idealist deserve an ancient place to gather their tribe.
Futurist who acknowledge the multicultural world we share shall inhabit the rest of the planet.
You're missing the point, the argument is that blacks would be even worse off if segregated.
Also, multiculturalism is only really occurring in Western countries.
China, the Arab states, India etc and most of Asia will remain the same and keep their culture. Not so in Europe.
Actually, China and most of the Asia are very nationalistic and regard citizenship as being racial. For instance, in Thailand it is absurd for them that those of non-Thai race can be in parliament or allowed to vote. Same in Japan, Korea, China, Vietnam, Cambodia, Myanmar etc.
