Yes. All the parties you listed are similar: ties to Russia, members that are literal neo-nazis, ridiculous views that contradict both history and science, anti-EU, anti-Ukraine, anti-media and blaming problems on immigrants without offering any solutions to problems that actually matter.
Comparing the AfD to the Green Party is a dramatic false equivalence. Thank you for quoting Popper, it’s the best argument for banning the AfD. They are not labelled “far-right” to dissuade people from voting for them, they are far-right because their inane views are so far from what is currently considered the political centre (which has shifted to the right HARD in the last decades).
