Every far right party ever, in any given country, has claimed and still claims that the asylum system of the respective country is 'broken'. That doesn't make it actually true. But in the history of right wing parties, the foreigner, the immigrant, the 'other' has always been the prime scapegoat, for any problem they could possibly conjure up.

Just after the German reunification, neonazis started violent attacks that targeted immigrants and asylum seekers. This violence has not stopped. Neonazis are responsible for a major part of politically motivated violence too.

But political parties like the AfD know the score. They formulate their programs in a way that makes it hard to find grounds for outright bans. To say that their program has to give grounds for a ban is short-sighted - that will never happen. They need to be judged by the things they say outside of their programs, and by the actions they commit and inspire.
