It's History
Now, I really (with added emphasis) don't like Fascism, but Mussolini's speeches are of genuine historical interest. The guy can't simply be airbrushed out of history (he was machine-gunned out and hung upside down in a garage, along with his mistress Clara Petacci). Sure, some fascists will play his speeches on their phones and get a warm, fuzzy glow, but historical documents can be used or abused for all sorts of purposes. (Anyone interested in a slightly dodgy dossier?)
