@lilbill15I meant to reply to this earlier but football and Midsommar got in the way. If you'd asked me 10-15 years ago if SD was akin to the UK National Front I'd most certainly have answered YES. SD has its roots in white nationalism and fascism but the last decade or so has seen quite dramatic reforms in their politics. Their present leader has done a lot to get rid of the 'hard-liners' . How much this has to do with reform and how much it has to do with their getting the party a bad name is hard to say. However, I'm pleased to say, that today there are no SD politicians going around weilding iron bars and attacking non-whites outside night clubs in the capital and today the SD party openly and officially rejects both fascism and nazism. SD is, however extremely nationalistic in its approach to immigration - something we are seeing in many other European countries' as well.
Because of the many changes for the better, I'd now liken SD more to Ukip. As I said, I don't like their ideology, but I do respect that they - possibly through the changes they've made within the party - are now the democratically elected third largest party in this country and as such - if democracy was working - should be included. They are instead totally frozen out by the so-called 'democratic' parties. This, and the fact that we have so many small parties, makes it difficult for any party to build a majority government without the aid of pacts being made (and broken - cause of the present crisis) both to the right, left and across the board.
Hope that gives you some clarity in the situation. Sorry you've had to wait.
