In common useage, this refers to political parties that are facist
leaning and deeply conservative. They are almost always slaughtered by the politically correct liberal idiots in the press and called Nazis, whether or not they actually practise any form of racism. The fear of what fascism has done in the past (ignoring the fact that governments fulfilling the definition of fascism include monarchies of mighty countries) has softened many media tools to believe that far right automatically means evil and bad.
There is no such thing as a good leftist.
