I am choosing to answer "Should 'hate speech' be censored by universities?" with this assigned rhetorical argument essay.
When students make arguments that seem hateful and threatening to any population of the the student body, the university's responsibility is to facilitate intelligent dialogue rather than censor, except in the case of genuine threats to the physical and intellectual integrity of students. One argument is that people who hold reviled positions on controversial topics often will mention taboo facts that need to be heard. "Hate speakers" need to be invited into and trained in the art of rhetorical argument; if they are not emotionally mature for this task, they could be assigned to academic probation along with something like Outward Bound.
