Googling the numbers I find that here in America since 911 about 30 Americans have been killed by Muslim terrorists or about 2 per year on average. Republicans put the number somewhere above 100 because they include non terrorist Muslims killing people they know.
I will even use 10,000 gun deaths per year rather than 33,000 which includes suicides. The math? American gun enthusiasts kill 5000 times as many Americans a year than Muslim terrorists. Thanks mostly to the NRA.
There have also been 52 Americans killed by right-wing American terrorists. So white Christian Republicans are twice as dangerous as Muslims.
