The Foundation of Individual Rights in Education highlighted a ridiculous case in my home state of Colorado earlier this week:

Two students at Colorado College were found guilty of violating the school's conduct code regarding "violence" after they distributed a satirical flyer mocking a publication of the Feminist and Gender Studies program. As part of their punishment, student Chris Robinson and a second student have been required to hold a campus forum discussing issues brought up by their satirical publication.
