Gee whiz...I don't seem to recall masses of Mideast Muslims turning out in droves to mourn dead Western victims of Isamo-fascist killers. I do recall stories of Muslims dancing in the streets and passing out candy after 9/11.
I am truly sorry for all innocent people who are victims of Islamo-fascism....or any other kind of fascism.
But because Westerners don't demonstrate their sorrow for Muslim victims of Islamo-fascist violence does not cause the Isamo-fascist killers to act the way they do. Islam causes them to act the way they do. That and very low IQs and a love of violence and degradation of females.
