The leader of the Freedom Front used to be a deputy minister, so they aren't that fringe.
Yeah, that's interesting. They are totally not treated as a pariah at all like similar parties in Europe would be. Both ANC and DA have worked in governing coalitions with them.
The VF+ has toned down the retoric over the years though. They no longer talk much about a volkstaat and instead portray themselves as a minority interest party. There was even an attempt to broaden there base. A few months ago they made a big fuss about a handful of coloured people that joined their party.
There is a new player in the game also. The relatively newly formed Front National (Front Nasionaal) was formed specifically to fight for "Afrikaner self-determination". From what I have seen, these guys seem very hardcore. Open apartheid apologists too. But they did very badly in the 2014 election.
