It's hard to fathom WTF modes of address have to do with the BNP but in a brave attempt to make it so, I found it very noticeable when at university in Germany in the 70s that the use of Herr, Frau & Fräulein was infinitely more widespread than the equivalents in Britain. And that racism was considerably more entrenched, indeed commonplace. Someone came to visit me in the house where I was renting a basement from the traditional old burgher. She enlisted the help of an African student (of which there were many: a case of German reparation in addition to the loss of the African colonies after WW1). Suddenly from aloft I heard screams of "Schwarz". Friend and black student descended followed by householder threatening me with eviction for harbouring visitors of the "wrong colour". On making inquiries at the police station I discovered that "no offence had been committed". Needless to say, I moved out anyway but we all know how Hitler's heirs treated the Gastarbeiter, don't we?
