Hate speech law : a philosophical examination IntroductionTen clusters of laws regulations codes that constrain uses of hate speech Principles of basic morality Principles of personal development Principles of civic morality Principles of cultural diversity Principles of political morality Principles of balance Principia juris Toward a theory of principled compromise Conclusion. Hate speech law can be found throughout the world. But it is also the subject of numerous principled arguments both for and against. These principles invoke a host of morally relevant features (e.g. liberty health autonomy security non subordination the absence of oppression human dignity the discovery of truth the acquisition of knowledge self realization human excellence civic dignity cultural diversity and choice recognition of cultural identity intercultural dialogue participation in democratic self government being subject only to legitimate rule) and practical considerations (e.g. efficacy the least restrictive alternative chilling effects). The book develops and then critically examines these various principled arguments. It also attempts to de homogenize hate speech law into different clusters of laws regulations codes that constrain uses of hate speech so as to facilitate a more nuanced examination of the principled arguments. Finally it argues that it is morally fitting for judicial and legislative judgments about the overall warrant of hate speech law to reflect principled compromise. Principled compromise is characterized not merely by compromise over matters of principled concern but also by compromise which is itself governed by ideals of moral duty or civic virtue (e.g. reciprocity equality and mutual respect)
