When you call somebody a fascist, you can mean any number of things. Often, it means no more than “somebody I don’t like.” It is an all-purpose epithet, usable by anyone against everyone from university deans to Fox News anchors. For that reason, the label should be used sparingly — saved for special occasions. As with “Nazi” or “Hitler,” it is often said that in any discussion, the first person reduced to using such a word has lost the argument. It’s ridiculous to compare any living person to Hitler or Mussolini.
