If you can point that out it will be helpful.
I personally think most people are oversimplifying it, by viewing the situation without context, using their own experience instead. After a joke about your baldness at the Oscars, there will be a lot of media buzz. And as a result there will be a lot of people chasing you around with cameras wherever you go, trying to catch glimpses of your hair loss, and trying to ask you questions about your balding. That being something you had already been through for several years, which has likely left you already traumatized. Maybe some people are strong enough that for them those issues are no big deal. Or maybe wealth makes it less a problem, they can just hide on an island somewhere if they want to get away. But many people are sensitive to this, and it does affect their mental health significantly. "It's just a roast" and they "signed up for it and got paid" is the hyperbole in my view.
I'm not saying responding with physical violence is excusable. Just that it is worthwhile to take a deeper look and have some empathy.
