One day after John Russell Houser killed two people and wounded nine in a movie theater in Lafayette, La., a picture is emerging online of a man caught up with a number of far-right ideas and fascinated about “the power of the lone wolf.”

“Do not mistake yourselves for one minute, the enemy sees all posted on this website. I do not want to discourage the last hope for the best, but you must realize the power of the lone wolf, is the power that come forth in ALL situations,” Houser wrote on a forum dedicated to the New York chapter of Golden Dawn, Greece’s far-right neo-Nazi political party. “Look within yourselves.”

That comment was one of dozens of messages that Houser, 59, left on several Internet message boards, all of which provide a picture of a politically disaffected, angry man who viewed the United States as a “financially failing filth farm,” expressed interest in white power groups, anti-Semitic ideas, the anti-gay Westboro Baptist Church, as well as a number of conspiracy theories often espoused by the antigovernment right.

But his extremism appears to have gone deeper. In 2005, he registered to attend David Duke’s European-American Unity and Rights Organization (EURO) Conference in New Orleans, according to a spreadsheet of conference registrations obtained by Hatewatch. He lauded Duke, one of the most recognizable figures of the American radical right, a neo-Nazi, longtime Ku Klux Klan leader and now an international spokesman for Holocaust denial. On a PoliticalForum.com, Houser wrote in 2013, “David Duke has been unseen or hear of in years, but at one time appeared exactly what US needed.”

David Duke (pictured) organized European-American Unity and Rights Organization (EURO) which claims to fight for “White Civil Rights” for “European and Americans Wherever They May Live.

Elsewhere online, Houser described his interests as “hustling” and said that his political involvement was minimal, though he belonged to a forum associated with Tea Party Nation. He sang the praise of Adolf Hitler many times, saying “Hitler is loved for the results of his pragmatism,” last January on the website stateofmind13.com.

Aside from his affinity for Hitler and Golden Dawn, he expressed racist extremism elsewhere. He promoted the disproven racist theory that a connection exists between race and IQ, and promoted The Bell Curve, a book written by Charles Murray. As for voting, he said, “don’t vote, waste of time.”

The shooting comes five weeks after Dylann Roof walked into a historic black church in Charleston, S.C., and killed nine people, adding to an ever growing list of attackers who, motivated by right-wing ideologies, have a left a growing body count of innocent victims.
