The far-right National-Democratic Party of Germany has put up campaign signs in Mecklenburg-Vorpommern with the slogan 'Ausländer raus'. In case you don't believe me, I've provided photographic proof. On closer inspection, the signs in fact read 'Kriminelle Ausländer raus', but this is more a vivid example of the pragmatics of font size, and other elements of graphic design, than it is a mitigation of the political view expressed. The NPD hovers as close as it can to the boundary which, if crossed, would place it in violation of the German constitutional ban on neo-Nazism. In the past decade there have been two failed, but close, attempts to have it outlawed. The MLPD, the Marxist Leninist Party of Germany, has made this one of their principle campaign issues in the current election, which from my American free-speech point of view looks like a frivolous distraction, as there are far better ways to isolate fascists than to give their organizations the extra charge of illegality. The National Socialist Underground has committed at least a dozen murders since 2000; an illegal NPD would be great for their recruitment.
According to a 2010 article in Die Zeit, in that year a constitutional court ruled that the phrase 'Ausländer raus' by itself does not necessarily amount to a violation of the constitution; the entire context of the phrase needs to be considered in order to determine whether in a given occurrence it is meant as a reference, or indeed a citation, of the phrase as it was used in the 1930s. Without the addition of 'criminal', however, the NPD would probably not be able to pass off the phrase that follows as independent from the identical phrase as used by the Nazis, as the entire context of the party's existence is the longue durée of fascism in Germany. But as it is they can claim, bald-faced, that they are only pushing for the same desideratum that even center-left parties support: the deportation of non-citizens convicted of felonies.
