I took the Wahl-o-Mat online quiz and it tells me I should vote for the Humanist party.

"(Die Humanisten) see themselves as a social, liberal and progressive party that focuses on the freedom of the individual. In doing so, she invokes evolutionary humanism and advocates a critical-rational political approach that relies particularly on scientific knowledge and - regardless of the political trend - is open to all effective political concepts."

I go through the 38 questions and compare my answers to the Humanists, as well as the SPD, and also the AfD, just out of curiosity.
