The German Greens used to be against war, militarism, NATO, racism and other good stuff. Now they're the most pro-war, pro-NATO, and arguably the second most pro-genocide party. The former vice-chancellor Habeck told all Muslims to get in line and apologize for Hamas and swear allegiance to Israel. A very senior token Turkish-German member painted Muslim immigrant men as potentially wanting toremoved his daughter.
They instrumentalize the Holocaust both to support the genocide in Gaza and support Nazis in Ukraine. They started doing this with the Yugoslav wars in the late 90s.
They gutted worker's rights many times, they're arguably the most neoliberal of all the bourgeoise parties. They want to privatize the trains even further, split them up and introduce more market competition in public transport.
The people who used to support them either went along with this, becoming ideologically committed Western cultural supremacists and neoliberals, more so I'd say than conservatives and socdems even, who sometimes have their moments of realism; or they left or were bullied out. The Greens and their base are true believers, they think the German liberal ideology is the peak of civilization and should be exported by force.
Because the Greens used to sponsor the anti-war movement, social welfare protests, and other leftish causes, them switching sides caused these movements to split and collapse. Most of these causes are now dead; people who still cling to them smeared as traitors by the Greens especially. The Greens were not just useless, they did lots and lots of damage, to many many causes. No class consciousness or anti-imperialism that I can see emerged from the Greens betraying all their past ideas.
So no, fucking please do not help these people. Literally any revolutionary org would be better than them. In fact, sitting on your ass all day is better than that.
