Freedom of expression is a means to education  Students need to be able to take chances and express unpopular ideas in order to maximize their personal growth and development. Speech codes, even ones designed to only censor hate speech, have a chilling effect on all speech as students become afraid to say anything that is not politically correct. For example a student at California Polytechnic State University underwent a day long disciplinary hearing for posting a flyer publicising a talk “It’s O.K. to Leave the Plantation”. [1] It would not be surprising if students are less willing to organise such events after such a dressing down. Students also need to learn to respond to ideas they don’t like because even if censorship of hate speech is effectively controlled on campus, it still exists in the outside world. Students will only be able to maximize their ability to ask questions, state opinions, and respond to ideas on a free campus.
