“the recent rise of the British National Party tells us anything about how a European society can be infatuated with the Left one year and switch over to fascism in a relatively short period.”

going from socialist to facist is NOT a switch or a flip.

a calm leftist is a socialist,
an angry leftist is a facist.

facism is only a little further down the same road as socialism and progressivism.

a calm rightist is a republican
an angry rightist is a patriot.
