Most college and university speech codes would not survive a legal challenge, according to a report released in December by the Foundation for Individual Rights in Education, a watchdog group for free speech on campuses. The report labeled many speech codes as overly broad or vague, and cited examples such as Furman University's prohibition of "offensive communication not in keeping with the community standards," and a ban on "disrespect for persons" at the University of North Carolina at Greensboro. The report also warned more than 200 colleges that they were "extremely vulnerable to a constitutional challenge." Three colleges recently revised their speech codes after the group filed lawsuits against them.
