University Catalog: Student Conduct- Purdue University Bill of Student Rights

Relevant Excerpt

[T]he student shall be free to discuss and express any view relevant to subject matter presented by the instructor or other class members.  However, in exercising this freedom, the student shall not interfere with the academic process of the class by speaking to or behaving towards others in a manner constituting unwelcome, targeted conduct that is so severe, pervasive, and objectively offensive, and that so undermines and detracts from the educational experience of those to whom the speech or behavior is targeted, that the targeted person is effectively denied equal access to the University’s resources and opportunities.
