'Cancelling' is a term that originated in young and progressive circles, where it was used to mean 'boycott,' University of Pennsylvania linguist Nicole Holliday tells NPR. Now the term 'cancel' has been co-opted and weaponized by some conservative media and politicians. Something similar happened in the 1990s with the term 'politically correct.' John K. Wilson wrote about that time in a book called The Myth Of Political Correctness. And — just like 'politically correct' — 'cancelling' and 'cancel culture' have been co-opted and weaponized to attack the left today. Social media has made that easier, says Jon Ronson, author of So You've Been Publicly Shamed.
