maybe given their history of literally accepting Hitler, Germans shouldn't be the ones policing what words can be used?

Given everyone's history, someone somewhere has accepted evil in every country, so no one should police what words mean?

I'd say stay away from policing at least one's own evils. People that are idiotic enough to connect the superhuman in this context to Naziism should stay away from policing any meanings (but now I'm guilty of policing what people should police)
