Illinois State University tries to curtail free speech.

Illinois State's Code of Student Conduct contains a provision entitled "To Be an Illinois State University Student," which sets forth a list of "non-negotiable values" at the university, including "civility," "an appreciation of diversity," and "individual and social responsibility."

The policy states:

These values are the hallmark of the University, and will be protected diligently. Each person has the right and ability to make decisions about his or her own conduct. Just as importantly, each person has the responsibility to accept the consequences of those decisions. When individual behavior conflicts with the values of the University, the individual must choose whether to adapt his or her behavior to meet the needs of the community or to leave the University. (Emphasis added.)

So by the plain language of this policy, if a student's expression or behavior deviates from the university's definition of what it means to appreciate diversity or be socially responsible, that student may be asked to leave the university. 

As a public university, Illinois State has no right to require its students to adhere to certain values as a condition of membership in the university community. If this is not immediately clear to you, just try substituting the word "patriotism" for any of the values on that list and imagine the university enforcing the policy.

Constitutionally speaking, this is not even a close call. The university can share with its students the values it deems important, and it can encourage them to agree. It cannot, however, exclude students whose otherwise lawful behavior does not accord with those values. This policy puts the university embarrassingly and dangerously at odds with the Bill of Rights, and it must be revised immediately.
