Student representative: Our university, in expelling a student who verbally harassed his roommate, has erred by penalizing the student for doing what he surely has a right to do: speak his mind!
Dean's Conclusion (implicit)
It was correct to expel that student for verbally harassing his roommate.
Dean's Evidence
Had we not expelled him, we'd be endorsing verbal harassment, but if we did that, it would threaten the free flow of ideas integral to university life.
Evaluate
Ideally we want to react to the Straw Man the dean starts with. The student never said that the university should endorse verbal harassment.
We could even construe this as the dean presenting a False Choice: either we expel the student for harassment or we endorse verbal harassment.
But isn't there a middle ground between those options? Couldn't the university condemn and even punish the harassing student without full-on expelling them?
Goal
Let's look for an answer calling out the way the dean misrepresents the student's statements or calling out the fact that there are other ways to punish/condemn besides expelling.
