I have no idea if the administration has ulterior motives and is trying to suppress the instinct or opportunity for activism. However, the world does not come with trigger warnings and safe spaces. The creation of same is an attempt to sanitize the environment where we ought to be cultivating the broadest, deepest, and therefore most potentially challenging dialogues, conversations, and debates. The college campus is the ideal place for these heightened exchanges because the young adults who are the dominant demographic on the college campus are attending to be exposed to the types of materials and stimuli that provoke intellectual, psychological, and emotional growth.
The administrators say rather straightforwardly that they expect civility, and that all speech is protected. If that is taken to be genuine, then protest speech is also being courted and expected.
Simply put, all topics should be fair came on the college campus. If the university truly has an issue with students with disabilities, and with their policies and protocols for responding to sexual assault, no legislation or safe spaces, trigger warnings or the like is going to change the quality of the environment.
If I were a professor there, I would urge students to take the administration at their word and deliberately initiate discussions of those topics which may make people uncomfortable.
