Estimating (generously) 10,000 homicides by gun per year in the U.S. since 9/11/01, that adds up to less than 150,000 total. And no indication if the perps were Christian, Muslim, white, black, or anything else, nor is it known if the victims all were "Americans." So when it comes to 500,000, Peggy basically is just making stuff up because she's not very intelligent.
