The meeting at the White House between Donald Trump and the South African president, Cyril Ramaphosa, was, at its heart, about the preservation of essential historical truths.

The US president's claims of white genocide conflict with the actual racial persecution and massacres that took place during the two centuries of colonisation and nearly 50 years of apartheid in South Africa.

It is not enough to be affronted by these claims, or to casually dismiss them as untruths.

These statements are a clear example of how language can be leveraged to extend the effects of previous injustices.
