Our general reporter, Professor Pizzorusso, has given us “incitement to hatred” - primarily against a group of persons defined in terms of race, ethnicity, national origin, gender, religion, sexual orientation, and the like--as the working definition of “hate speech”, and asks to what extent such speech is constitutionally protected in the reporting countries. The United States of America are known at least in recent times for providing exceptionally broad protection for otherwise objectionable speech and expression, and hate speech is understood to be one of the areas in which they have positioned themselves further out on the speech-protective end of the legal spectrum than perhaps most other countries have been willing to venture.
