What worries me about "cancel culture" is the slippery slope. It seems like a good idea to "cancel" people who use various types of hate speech, for instance. However, I think that even for those people, there has to be some chance to be allowed back into civil society in the future. People can and do change. Cancel culture doesn't seem to allow much - if any - room for redemption. If the aim is to create "safe", "welcoming" environments in which nobody can ever be offended by somebody else's speech, it seems to me that the only way to do that is to censor and restrict certain types of speech. It is only possible to create a "welcoming" environment of this type by actively excluding some people and making sure that they are not welcome. Cancel culture might have, at one time, focused on excluding actual Nazis, for instance - that is, actual white supremacists who call for the extermination of Jews, homosexuals, people of colour etc. Are we now at the stage where using the word "fat", for example, means a person can be labelled a "Nazi" and treated with the same kind of contempt and exclusion that would be given to an actual Nazi? The end result of this process, if followed to its logical conclusion, is that nobody will be brave enough to say out loud what they actually think, unless what they think fits a well-defined mould of "acceptable" thoughts. This means we risk ending up with a monoculture in which some ideas are approved for discussion while others are forbidden. We can't punish thought crime yet, but what if that becomes possible in the future? It is not the case that all ideas and opinions are equally valid. Some ways of living our lives are demonstrably better than others, for everyone. But I am wary about people who are more interested in punishing others for having the "wrong" opinions than they are about having discussions in which somebody might just change their mind about something. One other thing: everybody makes mistakes, at some time or other. How should we deal with people who make mistakes? What about people who, through lack of knowledge or forethought, say something that offends others - perhaps deeply - but later are honestly sorry about what they said? Will the Twitter lynch mob be willing to forgive and forget? Or is it once cancelled, forever cancelled?
