Hoffman and Ware argue in their book, Gods, Guns, and about how  and spoke to us at ASU about how violent extremism in the United States has been a story of a historical trajectory that they believe is well described by the title of the book. According to the two of them this variant of extremism which has existed in the US since at least the period of reconstruction by groups like the Ku Klux Klan, was suppressed in part by the creation of the Department of Justice at another time of insecurity in the country for the purpose of suppressing that violent extremism. The Klan was revived again in the 19 teens as well as 1920s and one more time in the 1960s.

The 1970s violence was mimicked in the current era. Particularly xenophobia, and  distrust and dislike of immigrants, the gradual unsuccessful ending of a quarter of a century war in South East Asia contributed to a malaise that upset many Americans, especially those who felt America was losing its greatness. At the same time in the 1980s members of various religious groups helped give some justification for the white sheet part of the Klan and the Brownshirts of the neo-Nazis from Biblical scripture. The religious right became an enthusiastic supporter of the political right. This mixture of right-wing politics and conservative religion became acutely toxic.

White Supremacist churches became active in support of the American right, particularly the church of Jesus Christ Christian attempted to unite a group that was actually very diverse. It included anti-government extremists, tax resisters, gun advocates, racists, anti-Semites, xenophobes, and militant anti-abortionists needed uniting, they thought. Many of the leaders of the political movement were also Pastors or Reverends who also led churches or organizations of churches.

The guns part of the movement became prominent in the 1990s. Terrorist groups according to Hoffman, always are looking for ways to broaden their appeal. They started to advance the cause for gun rights coupled with salient religious rights as well. During the Clinton administration gun enthusiasts became convinced that the federal government would try to expropriate their guns while the religious right accepted that, but was also deeply concerned about the perceived immorality on the left. This was exemplified by the what they thought was the absolute corruption and immorality of the Clintons.

It was this fear of losing guns and freedoms to an aggrieved federal government that inspired Timothy McVeigh to launch an attack on the federal building in Oklahoma City in 1995. 169 persons, many of them children, died in that attack and it is still the most lethal internal terrorist attack in the history United States. I remember when that attack occurred and how most people, including at first me,  assumed it had been caused by Jihadist terrorists.  That was where the fear of terror was born. No one thought at the time that home grown terrorists were a serious problem. That bombing changed that point of view.

Hoffman said when he first started his career as an analyst of terrorism 43 year ago, he was concerned about right-wing terror but that dissipated after 9/11 when American learned to fear Islamic extremism first with Al Qaeda and later ISIS.
