‘Weimar Republic was progressive’ is a propaganda take by Germany to make them feel like the nazis happened in isolation. Your understanding of the Weimar Republic isn’t materialist. Rather than talk about quantum mechanics which had no impact on the workers, you could talk about how the SPD killed Karl and Rosa and wiping out communists to make sure that there was no chance of a workers state. And look what it led to… So anyway I would say I’m not being hard on the Weimar Republic
