As a native German and antifascist leftist I'm worried as well, but I don't think that history will simply repeat itself. The problems we are facing are very different and I don't think that a party as radical as the AfD is able to gather 20% support in a federal election. Germany HAS become a multicultural wonderland in recent years and the majority supports it! German politicians of the left, center and center-right shouldn't engage in the blame game. Especially the CDU/CSU has to understand that their role now is not to copy AfD talking points.
I‘m using it right now and it is so snappy. Feels like Apollo all the way — it’s crazy.
