Take a black, Venda-speaking man living in the Limpopo region, and a black, Xhosa-speaking man living in the Eastern Cape. They can't communicate, they have different backgrounds, different cultures. But if we work according to the race demographic, they're both just black men. This is a flawed approach - 77% of our population is black. How can all 77% be exactly the same? It's impossible.
