I disagree with your "totalitarian measure" comment, it is the AfD who are not compatible with the German constitution and the majority of Germany's society who prefer a fair democracy should not bulge the shouting of demands by populists, Reichsbürger, Querdenker. The connections to the AfD do exist, AfD politician Malsack-Winkemann (then already not a member of the Bundestag anymore, a security issue in my eyes) toured through the Reichstag with people from the Reichtsbürger group around Heinrich XIII. Prinz Reuß. Local AfD politician Andreas Geitz was even part of the Reichstagsturm in 2020.
