> "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?
