ABSTRACT 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.

政客的仇恨言论和家庭恐怖主义

摘要仇恨言论（针对、,毁或意图恐吓社会中的少数群体和其他群体的言论）助长了国内恐怖主义？不幸的是，鉴于包括美国在内的许多国家中政治人物和国内恐怖事件对仇恨言论的使用趋于一致，这个问题是相关的。在这项研究中，我认为政治家的仇恨言论加深了政治两极化，而这反过来又造成了家庭恐怖主义加剧的条件。我使用2000年至2017年期间针对135至163个国家的恐怖主义和仇恨言论数据测试了这一主张。我得出了两个发现。首先，政治人物的仇恨言论助长了国内恐怖主义。第二，政治仇恨言论对国内恐怖主义的影响是通过加剧的政治两极分化来实现的。
