The number of Americans who have been killed by Islamic extremists in the United States since September 2001 is just 21 — less than two per year — and none of them on airplanes. Statistically speaking, you’re several times more likely to be fatally attacked on an American schoolyard: in just the year and a half since the December 2012 Sandy Hook attack, 28 people have been killed in US school shootings. And meanwhile, right-wing extremists — virtually all of them white — have killed 37 people since 2001.
