Is racial segregation completely incompatible with human rights? Is it possible there may be forms of racial segragation that are fair, or even desirable to the majority of people within both races?
Consider that there can be different extents of racial segregation, ranging from completely voluntary on both sides, to forced separation of different ethnicities into different nations. Indeed, on several occassions both the USA and UN have actively supported national separatism along ethnic lines (Serbia, South Sudan, Ossetia).
One form of racial segregation, for example, might simply be to offer racially segregated class rooms to students, so that a student could choose either a racially-mixed class, or a class of only his own ethnicity. The degrees of voluntary choice could be variable; for example a student of a certain ethnicity might or might not be allowed into the class designated specifically for a different ethnicity. Or private employers could simply be allowed to choose who they hire, using race as a factor if they so choose.
The United Nations has supported the 'International Covenant on Economic, Social and Cultural Rights'. Is it overreaching its original intentions?
There are, of course, several valid reasons people would want to be racially segregated. People generally prefer to be amongst those of their same ethnicity. And there can often be cultural frictions. Asian people often prefer to live under a stricter and more regulated society than hispanic people for example. Different ethnic groups comitt crimes at significantly different rates, which can lead to resentment from other ethnicities. Some ethnicities may simply just wish to preserve their cultural integrity and reduce the possibility of future assimilation.
While racial/ethnic segregation has historically often been used as a tool of oppression, I am just saying that the concept itself is not necessarily unfair.
