Having done a bit of research on this film (actually just glancing at the wikipedia page) I learned that in his biography Charlie Chaplin stated that he would not have made The Great Dictator (1940) if he had known the true extent of the violence committed against the Jewish people in Germany. Perhaps this would have been the right decision in 1940 when Hitler was still in power and the threat he represented wasn't widely known. Trivializing dangerous people can give them power by disguising their threat, however in 2019, to quote Mel Brooks, "Of course it is impossible to take revenge for 6 million murdered Jews. But by using the medium of comedy, we can try to rob Hitler of his posthumous power and myths."
