But your departure point is a wild and unproven assumption. A bit of propaganda, had it not been for Apartheid well then South Africa would be a prosperous, racially integrated society and there would be no inequality everything would be good.  If that is your departure point - then that "conversation" starts off with a lie. There is no reason whatsover that  South Africa could not have seen a racial civil war and perhaps even much worse off had things gone the other way.
