A study by the New America Foundation shows that right wing, anti-government extremists and white supremacists are a bigger threat to the US than Islamic terrorists.
Study claims right-wing extremists bigger threat to US than jihadis
The study is based on the number of those killed by each group since 9/11. Not only does it skew the results by leaving out 9/11, but it also ignores the many, many foiled jihad plots, as this story points out. Also, right-wing extremists like Dylann Roof, the murderer in Charleston, South Carolina, kill because of their paranoid fantasies, but are not part of any movement with an articulated agenda or goal, while Islamic jihadists are members of or ideologically aligned with groups that have declared their intention to destroy the U.S. and the free world.
