A brief aside to discuss the concept of race.
Race is a social construct. It may overlap with some linguistic or biological markers, but ultimately it's something imposed by power. Race is like money: it exists because the people with the guns made it up.
In South Africa, "Black" and "Coloured" are considered to be different races. This loosely corresponds to the traditional divide between Nguni and Khoi people, but "Coloured" also includes a lot of people with mixed heritage (which often goes centuries back - humans don't fit neatly into categories.) If a Black and a Coloured person were to travel to Europe, they would both be considered Black by European standards, but in South Africa there would be a divide, which just shows us how arbitrary race is.
There are, roughly, ten Black people for every Coloured person in South Africa; during the late Apartheid person, which is when the rest of this thread is set, White people narrowly outnumbered Coloured people.
