Like other German theorists of the state, Carl Schmitt held to the idea that politics is always about violence; if we really and truly disagree with other people, we ought to treat them as enemies. Fish does not follow Schmitt this far. To be sure, he fills his books with examples of people who ought to, and usually do, hate each other: secular liberals dealing with religious fundamentalists; full-stop opponents of affirmative action confronting those who support it; defenders of speech codes and critics of hate-crime laws.
