Or maybe it is the brainwashing of the Springer-press that continues to vilify the Greens
The German greens are the greatest insult to ecology and progressivism in the history of Earth. Born out of the antinuclear movement and immediately coopted by fossil fuel lobbies, the only thing they've done is to encourage MORE coal plants to be opened (due to pushing for the closure of nuclear plants), and supported every single neoliberal anti-welfare budget and every military intervention (think bombing of Yugoslavia, bombing of Libya, invasion of Iraq). They're seriously one of the worst parties in the EU.
