Id rather have a bunch of racists with freedom than a totalitarian society where people can only say a predetermined list of words and thoughts.
TN, we all deserve a modicum of respect as human beings, regardless of what "group" we have been roped into by another group. For a university to insist on that by its students does not seem fascist to me. Racism is corrosive and unhelpful to our society and there is no reason to welcome its soapbox into the public forum.
And totalitarianism isnt corrosive and unhelpful? LOL
Shall we discuss human history or no?

It wasnt even a school function. Thats some damn bullshit.
Are you giving your students punishment when they say something you dont agree with, when they are in their own homes?
Posting a rant on social media is not speaking "in their own homes."
I never would "punish" a student for voicing his/her opinion, but if someone started ranting a racist tirade, I would give a lecture on respect and yes, I would forbid "n*gger" in my classroom. I have plenty of students -- even some of our coworkers -- that are very conservative. We listen respectfully. So around here, students know to speak respectfully because that's how they are treated.
