Abstract: Cancel Culture is a defense of due process, free speech, and even-handedness in the application of judgment. It makes the case for restraint and care in decisions about whom and what to cancel, boycott, deplatform, and bar from public life, and offers recommendations for when, why, and to what degree these steps may be appropriate, as long as objective, fair-minded criteria can be determined and met. While Dershowitz argues against the worst excesses of cancel culture—the rush to judgment and the devastating results it can have on those who may be innocent, the power of social media to effect punishment without a thorough examination of evidence, the idea that historical events can be viewed through the same lens as actions in the present day—he also acknowledges that its defenders ostensibly try to use it to create meaningful, positive change, and notes that cancelling may itself be a constitutionally protected form of free speech. In the end, Cancel Culture represents an icon in the defense of free speech and due process reckoning with the greatest challenge and threat to these rights since the rise of McCarthyism. It is essential reading for anyone interested in or concerned about cancel culture, its effects on our society, and its significance in a greater historical and political context.
