I'm confused, do you seriously think the AfD runs on phrases like "we want to get rid of the democratic system"?

It's actually quite the opposite, they are running on things like a direct democracy[0], with phrases such as "Wir sind überzeugte Demokraten"[1] (eng: We are confident democrats). And they do that for good reason, as running a party that openly wants to abandon the democratic process would be against the constitution.
