I am old enough to disdain cancel culture, though not for the reasons the letter gives. My disdain comes from the belief that it doesn’t exist — at least not as anything new, anything more than yet another term used as a blanket criticism of people, often young but not always, deploying new forms of communication (in this case, social media) to call out those they believe are espousing or enabling racism, sexism, homophobia, transphobia, sexual harassment and capitalistic exploitation. (Or, less grandly, to promote inter-influencer feuds.)
