Speech Codes and Stuff

What are speech codes? Speech codes are policies made by schools to restrict hateful speech. This speech would be protected under the First Amendment if the school did not make a specific rule against it. If the school did not declare hateful speech illegal people would find loopholes in the law until the law stood for basically nothing. I think that there is too much grey area in the First Amendment. With the use of speech codes, academic institutions can restrict speech to the means they feel necessary. I think speech codes are a good thing. A school has full rights to maintain their reputation of comfort and freedom for all races/genders. It is pretty obvious when a school abuses their speech code power and i am confident a group of students would challenge their power.
