One person was murdered in a likely terrorist attack in Charlottesville, Virginia this Saturday when a suspected white nationalist named Alex Fields Jr. drove his car into a group of protesters. Prominent people on both sides of the political spectrum have condemned the politically motivated violence. However, some commentators have pointed out that left wing terrorists and rioters have also committed violence in recent years, though they have not provided any data with which to compare the relative scale of the violence. This blog fills that void by describing terrorist murders and injuries by the political ideology of the perpetrators. Also, though the chance of being murdered or injured in a terrorist attack is minor, there is wide variation in the ideology of terrorists.
Data and Methodology
This post examines 25 years of terrorism on U.S. soil from 1992 through August 12, 2017. Fatalities and injuries in terrorist attacks are the most important measures of the cost of terrorism. The information sources are the Global Terrorism Database at the University of Maryland and the RAND Corporation. Other organizations seem to count many religiously or racially motivated crimes as terrorist offenses, an overcounting that I attempted to avoid. I estimate the number of murders committed by terrorists in 2017 from online sources although they may be incomplete. As much as possible, I excluded terrorists who died or were injured in their attacks as they are not victims.
I grouped the ideology of the attackers into four broad groups: Islamists, Nationalists and Right Wingers, Left Wingers, and Unknown/Other. Global Terrorism Database descriptions of the attackers and news stories were my guide in organizing the groups by ideology. Islamists and unknown/other straightforward. Left Wing terrorists include Communists, Socialists, animal rights activists, anti-white racists, LGBT extremists, attackers inspired by Black Lives Matter, and ethnic or national separatists who also embrace Socialism. Nationalist and Right Wing terrorists include white nationalists, Neo-Confederates, non-socialist secessionists, nationalists, anti-Communists, fascists, anti-Muslim attackers, anti-immigration extremists, Sovereign Citizens, bombers who targeted the IRS, militia movements, and abortion clinic bombers. Some of the marginal attacks are open to reinterpretation but the ideology of the attackers by death and injury are straightforward in virtually all cases.
