Is it wrong to have an all-Black student dormitory at university? What about an all-white dormitory?

I think it is wrong to have dormitories that split people into any ethnic, racial, or sexual groups. This is just as bad as the problems southern America faced in the 1960s: Black students not being able to attend the same schools as Whites, use the same drinking fountains, or sit in the same area on the bus. It prevents Caucasian and Black people from having the same privileges or sharing the same space, and there is no reason for it.
