We are all aware of the barbaric acts of ISIS, al Qaeda and the others flying the Black Flag. Sadly their violence continues to kill innocents around the world and here at home. They fight in the cause of Jihad to impose their totalitarian religion on all people. But they are not the only ones working toward that goal. There are other Islamist groups who seem much less dangerous on the surface, but actually represent an even more insidious threat to free western society. They seek to use our very freedoms as weapons against us.
