Reduced dialogue  While hate speech is a form of expression, it is not one that encourages dialogue. By promoting hatred based on immutable personal characteristics it is by definition anti-dialogue. Hate speech does not contribute anything; it merely provides a justification for violence and discrimination. Extreme messages, be they in words or through symbols, deter moderates from voicing their opinions, either because they do not want to legitimize the message or out of fear of reprisals. This reduces the net dialogue on university campuses and injures the quality of the dialogue that remains.
