@Alan McDougall,
Do you think that separation, or a socially fair and just version of apartheid, is sometimes a better answer than trying to assimilate peoples who do not care to integrate with each other?
I'm thinking of the semi-autonomous Cossack communities in Russia -- they prefer separation, but in return for this privilege (semi-autonomous rule, not serving in the military or police, still retaining Russian citizenship), they volunteer for "independent contracts" which no one else really wants: for example, border patrol and policing "hot" zones, especially near Chechnya. They are a warrior class.
BTW: I think S. Africa has an incredibly beautiful national hymn? anthem? Nkosi Sikelele Afrika? (am I even close?)
