It is estimated that there are 2,000 to 100,000 Muslim insurgents. This includes the most conservative and liberal estimates.
There are about 1.2 billion Muslims in the world.
There are about 12 million Mormons, which makes the math very easy.
Therefore, we simply need to find 20-1,000 militant Mormons, or people who call themselves Mormons (since anyone can call themselves a Muslim), and we can brand Mormonism a violent religion. How simple.
