So the most popular party among English speakers is the one in Saxony that recently submitted a formal inquiry about sterilizing refugee children. Fantastic. As I've said for a while, all the right-wing cries of "freedom" are simply a cover for the preservation of their power and privilege. Thankfully Germans are smarter than Atlas "Conservatives."
As for my vote, I'd probably have to vote for Die Linke. The SPD still seems pretty sold on the "neoliberal" agenda of the past 40 years. We need to move past that already; it has been a total disaster.
If the German voters were that smart, they would not have supported ruinous policies that naturally led to the rise of an entity like AfD. The house is on fire and nobody is willing to talk about it. What's worse is that the nature of the EU means that the migrant crisis is not restricted to Germany either, but shared among the nation-states.
Or perhaps AfD arose in response to the crisis only among the society's most bigoted and nationalistic members. Last I recall they can't seem to escape 10-15% support in polls. Germans may not be enthused about the crisis, but they don't take such a hostile view to it as Americans who don't even live in Europe do. 85-90% of Germans still support political parties that have, to some extent, embraced the intake of refugees. So the perception of those policies being "ruinous" doesn't seem to be a very popular one among Germans who actually live in Germany; only to people such as yourself, who presumably lives in California - thousands of miles away.
Also, it's nice to see that you completely dodged any response to the fact that you support and defend a party that has inquired about euthanizing refugee children. I guess that's just a trivial detail to you. But you'll certainly keep going on about "limited government" or "freedom" or whatever.
