same here... I tend to think left and green - but I also prefer supporting personal responsibility and freedom. Not a Topic of the "Linke". And I have some fears the Greens want to create a "Ökokratie" (hope the not German speaking understand my neologism
)
social democrats is no alternative for me because of the reasons you mentioned - they are not very social any more...
I often used to vote for the Greens, but as the situation is now, I think more open borders, humanitarian morality and tolerance towards immigrants is not what we need -- IMO, there are times when such ideas are useful, but right now, we need more emphasis on demanding integration efforts from immigrants and limits to immigration, and battling the negative effects of the refugee situaion. Less hippie chatter and more tough talk about the bad sides of immigration. So no Greenies right now.
But the AFD is too unappetizing, some really disgusting people in there who hate immigrants for all the wrong reasons -- plus its economic policy ideas are hardline neo-liberal. And most of all, that party has not decided yet just how pro-constitutional it's going to be. So no option for me.
The growing material inequality is a nagging problem IMO. But whom do you vote for, about that? The SPD gives me no reason whatsoever to consider voting for it. It's neither fish nor flesh, a CDU light or a Linke light, somewhere in between, but no clear line.
So the Linke? I like many of their domestic policy ideas, but no way I'm going to vote for them on national level. There are quite a few freedom-hating grade A commie nuts in that party. And their foreign and defense policy ideas are ridiculous, if not outright dangerous and even treasonous. The fact alone that some of their leading members write congratulations to freedom-hating tyrants abroad makes me nauseous, and their cheap, naive, stupid pacifism is pukeworthy, IMO.
That leaves the FDP. They may not share my views on material equity, but I 100% trust them when it comes to pro-constitutionalism and civil rights. If any party has respect for our free political system, understands it and knows why it's a good thing, it's the FDP. Of course, the "old FDP" of Westerwelle and Rösler was a joke, but after their disaster in 2013, they deserve a second chance and the benefit of the doubt -- we'll see how serious they are about a new start. Hopefully they'll indeed place less emphasis on free-market radicalism and more on civil rights -- not least since some prominent former Pirate Party members joined the FDP. Plus, Lindner makes a good impression one me, he appears smart and rhetorically skilled. And the FDP remained critical of Merkel's refugee policies, without overshooting the mark -- "Rechtsstaat statt Rechtspopulismus" is just a slogan, but if there is actually substance behind it, it goes into the right direction, IMO.
So yeah, for the lack of better alternatives, I told the Forsa guy I'd vote for the FDP.
