DEAR MISS MANNERS: It would seem that we have lost the art of social shunning. There are two new versions: Shaming and Cancel Culture. Miss Manners congratulates you for refraining from using these weapons casually. Miss Manners is bewildered by the current explanation of wrongdoers: “That is not who I am.”Well, then, who is it who did what you did? Miss Manners is not without mercy in viewing those accounts.
