Some of the white ones have been in the Western part of South Africa for about as long as the Bantu have been in South Africa (1600s).
Black South Africans (non-Khoisan, so the Bantu ones) only entered the Western portion of what is today South Africa very late in history.
They have been there long enough but are migrating back to Europe and Anglo-saxon countries like Aus, Canada and USA in large numbers. Cadaans can say they came at the same time as Bantus to western portion, but their actions tell us that they have given up.
