> "all white" in South Africa is a minority struggling against majority. They can't be "far right". Far Right means nativists which in South Africa continues to be black people and not white.

I don't think that most people understand 'far right' in that way. For example, are you saying that someone whose political philosophy hasn't changed, but who moves from one place to another, might go from being far-right to not, or vice versa?

Their quarrel is with the government not the black majority. There are plenty of black South Africans struggling in that system as well.

Historically, you're right. But the meaning of right/left changed post WW2 (some would say WW1), at least in most european countries.

South Africa is not in Europe. It would be stupid to use European connotations for non-European countries. At this rate western media might call Hindu temples in India "churches".
