Rory, something that can be said for this controversy is that it has been going on for only five years (so far). The disagreement about the statue of King Shaka that was intended for the entrance of the international airport named in his honour is still unresolved after 10 years, while the wire mesh and bits of concrete statues of elephants intended for the N3 road entrance to Durban have, as far as I know, now been used for landfill instead. Many people now wish a similar fate for all the statues and other memorials dating from the Colonial and Apartheid eras, but our leaders would be wise to wait for a generation or two, otherwise visitors to Durban will have no such street furniture to photograph.
Frank, there is a great deal that we, the hoi poloi who live in the Kingdom of the Zulu, do not know about the Zulu Royal Famil(y/ies). For example, the eldest son of the present Zulu King died recently in mysterious circumstances. There were brief mentions of a possible crime and a police investigation, but as far as I know the man simply died, was buried and it is no longer newsworthy. There was also an official denial that the Prince was heir to the throne, so evidently the Zulu Royal succession is determined by criteria other than lineage.
In this country one can suspect selective reporting (aka censorship), but that should not apply to foreign media. However, I suspect that they may be kept in line by wokes, 'black lives matter' and the widespread embarrassment about Colonialism, Apartheid and other such evils.
