There is more unpredictable danger from homegrown U.S. terrorists who don't respond to ISIL propaganda.

Marathon bomber Tamerlan Tsarnaev followed Alex Jones right wing extremist Infowars radio and Stormfront white supremacist websites. Christian and Odeon worshipping terrorists follow the same websites and radio broadcasts. 

Sara and Todd Palin were Alaska Independence Party members before they were Republican. The Alaska Independence Party has connections with Ulster nationalists and Chechen separatists. 

Tamerlan Tsarnaev is of Chechen descent but his hate comes in part from right wing extremist propaganda. 

Once government hating people get to a certain level of hate, ideology takes a back seat to pure hate. They want to take action and start killing. 

Sometimes killing becomes more important than who is killed. Like Fraser Glenn Miller:

 “My morale is super high, higher than ever before,” Miller added. “I’m totally at peace with myself. I struck violent blows against the GD jew [sic] menace – effective blows, too.” 

None of the three people Miller is accused of murdering on April 13, 2014 – William Corporon, 69, Corporon’s14-year-old grandson, Reat Underwood, and Terri LaManno, 53 – were Jewish. 

“I’ll die with a clear conscience,” Miller said in the letter, apparently mailed in early June, “knowing I did my best to secure the existence of ourt [sic] people, and a future for White children.”

Lone wolves don't necessarily care who they kill. They are taking action and the killing feels good.  

"A 19-year-old newlywed and former Mississippi State cheerleader. A Bosnian immigrant and war veteran. The son of a Boston area police officer. These are some of the 56 people arrested in the United States this year on charges of supporting or plotting with the Islamic State in Iraq and the Levant (ISIL) — the most terrorism-related arrests U.S. authorities have made in a single year since 2001. 

That finding is part of a new study from researchers at George Washington University who examined legal documents tied to ISIL-related charges in the U.S. since March 2014. What they found was an unprecedented diversity of ages, backgrounds and locations among ISIL's U.S.-based recruits — from the “keyboard warriors” who share the group's propaganda online to those who actually take up arms in Syria and Iraq. 

The information explains the challenge ISIL poses to traditional law enforcement protocols for clamping down on violent radicalization, said Lorenzo Vidino, director of the Program on Extremism at GWU and an author of the report. “There’s absolutely no common profile,” Vidino said. “ 

"From teenagers to people in their 40s, people of extremely diverse socioeconomic backgrounds, men and women, Caucasian, Latino, African-American, Jewish — you name it.”Unprecedented diversity of support for ISIL in US, study says."
