That’s just it. The only examples given are those who arguably did deserve the “canceling” that they got.
I haven’t seen any examples of people being harmed, just losing platforms provided by companies or organizations that choose not to endorse and support the statements that their associate chose to make in public.
The small damage that could be said to have been inflicted on them, which is arguable, in that often “canceling” backfires by bringing something to more people’s attention, has not been demonstrated to have been punitive or out of proportion. If canceling is attempted and fails, the cancelee often benefits, as JKR did when the fundamentalists and other highly religious folk provided her with free advertising.
The “Million moms” try to cancel anything fun, and so provide nothing more than a platform to see what is interesting enough to raise their hackles. Is anyone condemning them? I hope not, they have provided us with a great service.
The examples given are those who are powerful and influential. The reason that the criticism of them is so intense is because of that. They are powerful and influential. They are putting the weight of their power and influence behind the positions that they advocate. Me being some random guy on a messageboard, I have no more influence than I can earn with my words. If I revealed to you that I was famous author Neil Gaimon, then suddenly, I bet you would consider my arguments with more weight.
If there is any goal to “canceling”, it is to remove the platform that is legitimatizing and amplifying an opinion that is objectionable. It is not an attempt to shut it up, it is only an attempt to force it to compete on an even playing ground.
The words that JKR has said have been harmful, and she has not taken them back or apologized. Her mocking tone legitimizes mocking trans people, it delegitimizes their entire existence. Real people can receive real harm because of what she chose to interject into the public sphere. Cutting down her platform in response, or at least attempting to, is not an unreasonable reaction.
If JKR just straight up said, “Trans people should not be respected or accepted in society.” How much damage would that do? People would believe her, and follow her without thinking, because of the platform that she is given. I am not saying that this is what she believes or what she would say, just giving an example of the power and danger of giving someone that much social power.
With great power comes great responsibility, and so, I do think that they should take responsibility for the consequences of their words.
Examples of anyone losing their ability to earn a living have not been forthcoming. If I could see examples of everyday Joe losing everything because of some joke in poor taste, then I could see where the actual concern is coming from.
I will go ahead and also say that I do not consider death threats and such to be a part of cancel culture, if only in a no true Scotsmen way, and if you object to that distinction, and insist that it is, then I will say that it is a part that I will categorically condemn and not defend. Any defenses are solely of criticism and financial support of people choosing to advocate their views in public.
Profanity laced tirades on twitter or facebook or youtube are a different matter. I don’t see the good they do, but they don’t really do any harm either. You don’t even have to listen to them, and if it made someone feel good to get something off their chest, then it’s a net win. I don’t really defend them, but I can’t bring myself to categorically condemn them either. Depends on vehemence and persistence, but if actually crosses over to threats of physical harm, then is entirely unacceptable.
