I would object to the term "explicitly". I think it was implicit, and no violence was actually committed.
The point is that she said something stupid, and it was caught on camera. Let me assure you that I think it was very, very, stupid. Really bad. I can't remember exactly what I said about it at the time, but I was seriously anti-Melissa Click.
But should she lose her job for it? Did it affect her ability to teach about "Twilight"? (As I recall, she was an authority on the "Twilight" series. Why you would want one of those on your campus I'm not sure, but that's neither here nor there.) I think, instead, that what really happened is it went viral and a lot of right wingers, especially Republican legislators, applied pressure to Mizzou to get rid of her.
Because it happened on campus and involved interaction with students, you can stretch it and say that maybe it was related to her job, so perhaps it was justified. Sometimes, "cancel culture" gets things right. So, perhaps that is one more thing that you would never do, so you don't have to worry. You wouldn't have a public racist meltdown. You wouldn't call for "muscle" against.....anyone I suppose, but especially not a student journalist. You wouldn't insult the national anthem......or would you? You wouldn't encourage anyone to shoot a police officer.......er.....well......you would, but there are special circumstances and.........I think treading lightly might be a good idea.
