A complication that the 1619 Project brings up is that there are different actions which might reasonably fall under the heading of "banning". For example, repeated problems corroborating particular narratives in Elie Wiesel's Night led that book to be stocked in bookstores, but shelved under "fiction". Until someone started raising complaints in the media, at which point there was just as little corroboration but stores started shelving the book under "nonfiction" anyway.
