No ofcourse not. But Germany isn't a nazi regime today like it was back then. It's "just" one party that has grown the past years. Those protests show that the silent majority won't let them assume power and that we have learned from history.

Germany has a very strong democratic system and there are a lot of democratic ways of getting rid of such a party in a democratic way. For example it is likely that their funding is beeing stopped, so they have to finance themselves. Additionally it's highly likely that part of their party is being forbidden. And Germany even talks about forbidding the whole party. That's something the court has to decide.
