Replication Data for: Politician Hate Speech and Domestic Terrorism

Does hate speech – rhetoric that targets, vilifies or is intended to intimidate minorities and other groups in society – fuel domestic terrorism? This question is, unfortunately, relevant given the convergence of the use of hate speech by political figures and domestic terrorist incidents in a variety of countries, including the United States. In this study I theorize that hate speech by politicians deepens political polarization and that this, in turn, produces conditions under which domestic terrorism increases. I test this proposition using terrorism and hate speech data for 135 to 163 countries for the period 2000 to 2017. I produce two findings. First, hate speech by political figures boosts domestic terrorism. Second, the impact of political hate speech on domestic terrorism is mediated through increased political polarization.
