Is this the part where I highlight that Peden is a public facility and thus free speech rules apply?

Calling the Dragon...

Cohen is still a fine line.  Political vs. otherwise.  Since the MD/Duke incident a few years ago, MD now has a policy where they can eject, but not arrest.  The back of the ticket for many public university events now has a statement similar to the following:

Abusive language or disorderly conduct is unacceptable and unwelcome.  Profanity, racial or sexist comments, or intimidating actions directed at the student-athletes, coaches or officials will not be tolerated. Fans who display unsportsmanlike behavior may be ejected from the stadium and lose all ticket privileges.

Nebraska states it as following: The University of Nebraska promotes good sportsmanship and conduct among our alumni, students and friends. Inappropriate conduct, activity or any discourtesy should be reported to stadium personnel (fan hosts, gate attendants, vendors, etc.) or the Athletic Events Office at (402) 472-1960.

The reality is that it is easy for the University to find "another reason" to eject the fan - e.g., not cooperating with law enforcement and not rely on the language. 

It's also a bit of a pain when I'm bringing parents to the game as I did Saturday.  If I wanted to sit with them, and not purchase a ticket for myself (which seems a bit stupid, given I pay plenty through my fees and receive free tickets as a student), my and the girlfriend's only option to sit with them was to sit in the (sold) seats next to them and be thankful there were seats a row behind unsold that the gracious rightful owners of our seats could use.
