Not wanting to stir more trouble, but White South Africans come in different guises. It is those of Boer/Dutch/Norvegian origin who speak Afrikaans who do tend (trying not to stereotype) to have extreme views- those whose parents/grand-parents were responsible for the Apartheid regime, and still hark after it to this day. And also those of Huguenot French origin, who were also 'responsible' like the families of the infamous Eugène Terre Blanche, a nasty piece of work.
Those of English origin tend not to have such extreme attitudes.
My OH family at the time of Apartheid were in the worst possible situation- a mix of Norvegian, Dutch, Black African, English and Indonesian- living in the Malay quarters of Cape Towns- and with children in all shades- neither one group, nor another. Hence OH's parents decision to emigrate to England.
