The rambling settlement is several ghettos within one large ghetto. You have the Xhosas in one suburb, called Siyanyanzela, meaning, The land we took by force, which they did through conflict with the landowners, police and anybody that objected. Adjacent is Naledi, meaning Peace – conceptually, diametrically opposed in philosophy. The ghettos are a mixed community of ancestry.
The coloureds, depending on hierarchy live in Pineview, Snake Park, Beverly Hills and Melrose Place. There are other suburbs which I learn of every day. The Zimbabweans, Zulu, Somalians, Nigerians, Malawians and other foreign ethnic groups fit in where they are accepted.
In-between, gangsters, drug dealers and robbers live; hence the barbwire. But less so in Siyanyanzela which is 100% Xhosa. In one sense that 100% is like barbed wire. If you are not Xhosa you will be instantly spotted like a snooping drone.
