I had to dig into some other articles on this to find the name of the group Matthews is affiliated with. Its name is
The Base, which I note would be English for "Al Qaeda". They emulate Hitler and Charles Manson and train in sniper tactics. They have been involved in a series of anti-synagogue vandalisms called "Operation Kristallnacht", linked to
Atomwaffen Division, which espouses a similar Satanic Nazi ideology akin to the Order of Nine Angles, a group linked to several recent mass shootings:
Atomwaffen also draws influences from Nazi esotericism and the occult, and its recommended reading material for aspiring initiates includes the works of Savitri Devi and Anton Long of the Order of Nine Angles, a notorious British neo-Nazi leader with a violent criminal history.[22][25] Some members of the group also sympathize with the Salafi and jihadist forms of Islam. Atomwaffen Division's founder, Brandon Russell, is alleged to have described Omar Mateen, who pledged allegiance to the Islamic State of Iraq and the Levant and perpetrated the Orlando nightclub shooting, as "a hero". The group also idolizes Osama bin Laden in its propaganda and considers "the culture of martyrdom and insurgency" within al Qaeda and the Taliban as something which should be emulated.[31] Samuel Woodward also articulated a positive view of Islam, saying that he preferred ISIL to multiculturalism and liberalism and cited Julius Evola, Francis Parker Yockey and George Lincoln Rockwell as having been sympathetic towards Islam as well. He also said that Arthurs believed that Islamophobia was being used to promote White Genocide by Neocons.[1].
