A new tally has confirmed white supremacists and other non-Muslim fanatics have killed far more people in the United States since 9/11 than Muslim extremists. The report by the research center New America finds, since 9/11, white supremacists, antigovernment extremists and other non-Muslim figures have killed nearly twice as many people as Muslim extremists. Despite the intense focus by the Obama administration on Muslim communities, non-Muslims have carried out 19 terrorist attacks since September 11, 2001, while Muslims have been responsible for only seven.
