The south is generally very save and the cities are quite left-leaning. On the countryside and in smaller towns and cities you do see shit like you mentioned, though. Your Biden are our Greens and Habeck or Baerbock in that case, but definitely the same shit. Not as blatantly and openly as in the US, though.
There are definitely worse scenarios. The worst I know states that most parts of the world will be uninhabitable by humans and estimate that there will be 1-1.5 billion survivors by the end of the century. So, end of our species? No, just too damn close for comfort.
