:::: The book by the political sociologist Jens Rydgren clearly state that the SD is a Xenophobic and racist party, on Ethno pluralist grounds (at least it is his conclusion after an analysis of the party's programs). He has writen lots of scientific articles stating the same thing, and has been internationally published. If that is a credible sources of the highest quality, that would do. There are lots more books by scientists and journalists stating the same thing. What more does Gun Powder Ma demand? 
 :::: In my book the SD is stil a racist party. Everything in their on programs points at tread of cultural and biological racism. However, I think we should start the article with the fact that it is a far-right nationalist party. It says more about the party, in a neutral way then the epithet Xenophobic. The facts of the party's xenophobic / racist ideology can be accounted for later.
