They very much expect the SPD to defend things like co-determination laws to the death, though. They also expect the SPD to implement referenda that say that landlords with over 1000 apartments should be expropriated, that they’re dragging their feet on that kind of stuff (“but the markets might get uneasy and that would have consequences”) is one of the reasons why they don’t poll well.
Can you imagine a US city the size of Berlin pushing through a referendum to expropriate landowners? That’s how far apart the overton windows are. There’s hardly even overlap.
IDGAF about what the US is cooking up when it comes to political definitions, much less so when they disagree with the rest of the world. Anti-capitalism is necessary to be on the left, it’s not negotiable.
Just like you wouldn’t call someone who denies god a Christian. There’s no “but they deny god a bit less than Richard Dawkins, so they’re more Christian”: No, they’re still denying god, they can’t be Christian. If they consider themselves Christian despite denying god, then it stands to reason that they’re quite confused about what being a Christian entails, don’t you think?
