The FDP is to the right of the CDU these days anyway...
The FDP is very socially liberal and that is more important to me than anything else. It isn't as if they would cut everything like Republicans are trying to. I can't say how I'd truly feel unless I lived in Germany I suppose.
The FDP originally voted against legalizing same-sex unions back in 2000.
Of course, we don't really have "social issues" here anymore, so it doesn't matter.
The CDU/CSU aren't against abortion? Kind of weird.
Technically they are, I guess.
It's just not an political issue, meaning no political party íntends to change the status quo (which is that abortion is technically illegal, except that the law remains unenforced if the abortion is conducted during the first trimester).
