You're mixing up your arguments. colmvp said that words can hurt - and in response, you're retorting that students are asking for imprisonment of a professor? What? How is that a rebuttal? Regardless of whether the students are successful or are laughed out of college, it has no bearing on colmvp's comment that words can hurt.

Basically you're trying to force a false dichotomy, where the options are "nothing at all" and "complete destruction of life". Someone's opinion on such a ridiculously polarised fantasy isn't going to grant any useful insights.
