I know. I'm just laughing at you
It seems like both of you are very confusedly, and mistakenly, agreeing with each other.
When people criticized cancel culture, what they meant was the attempt to prevent anybody who disagreed with a certain regnant point of view from having any public platform. This was justified based on the idea that certain people hearing differing viewpoints would feel so bad about it that it would create an unsafe environment. Thus, you couldn’t allow somebody who disagreed with “trans” ideology speak in public or post anything on many social media sites, let alone publish something in a mainstream media outlet. And if somebody were to argue that police weren’t indiscriminately killing black people, then it was OK to prevent them from having any public platform not only by trying to prevent them from getting speaking opportunities, but also by shouting them down and rioting to prevent them from being heard. The issue is/was the idea that it was dangerous to allow different viewpoints from being heard, so it was actually virtuous to deplatform everyone you disagreed with.
Further, the problem is/was less that there would ever be any censorship, or that all speech was always appropriate, than that even in venues and media explicitly committed to open debate and deliberation, or in situations that had nothing to do with promoting a certain kind of politics (workplaces, sports, etc), people were being canceled for having the wrong (ie. not progressive) views.
There is/was also an aspect to cancel culture where people were going fishing for potentially objectionable things in someone’s past, and then using them to try to hurt that person. It was way too frequent that somebody would find something somebody said on social media in high school, years ago, when nobody seemed to have been hurt or to have cared, and then use that against somebody. Even though this was more recent, it looks a little more like that.
But I do think you have to make a distinction between being indecent and being ‘wrong.’ People shouldn’t be cancelled for being ‘wrong,’ in nearly all cases. But I don’t think most people have a problem with not giving a platform to an indecent person.
All that said, I do think many of the people who rightly complained about cancel culture a few years ago don’t seem to mind using the same kind of power used against them and people they agreed with. That just probably goes to show that being liberal minded- which is what belief in free speech means- is actually pretty rare.
It’s also probably wise to let your first response to somebody being assassinated be sympathy and grief, rather than trying to score political points. I don’t know why a guy like this professor felt like he had to say this immediately.
