 On the presumption that hate speech is harmful—both particularly harmful for the members of targeted groups, and also generally harmful to democracy—the natural question that follows is: what should we do about it? This question, however, rests on several sub-questions—some empirical, some conceptual—that themselves admit of rich dispute. For example, depending on how one conceives of the value and point of free expression—to better seek the truth, to respect autonomy, to ensure democracy, etc.—different answers to the hate speech question will seem more worthwhile than others. The same consideration applies to empirical matters as well, which are often difficult to properly assess in the absence of uncontroversial data. This means that relatively straightforward empirical questions—does genocidal speech pave the way to actual genocidal violence; do governments abuse hate speech regulation to punish political rivals and disfavored minorities; and others—rarely receive unanimous agreement. Despite these challenges, many theorists have addressed the question of how to counteract hate speech, and what form that response ought to take.
