Christians fight when we must, and have the means to, for a just cause. Our most powerful weapon is our faith. To give it up is to give up the fight for God's truth in this world. "These people" are also human with hearts, despite how badly they've been led to believe they must kill or "convert" others. The Holy Ghost may enter any human heart given the slightest opening. Seeing the courage of a Christian who won't lay down his weapon in the fight against evil may be that slight opening.
Lots of luck. I just think that when they execute Jews and Christians for being what they are, there is no hope for them. These people are blinded by their crazy religious belief and by hatred. They do not care - and in fact - encourage children to blow themselves up. Even the nutty Nazis didn't tell their kids to become suicide bombers (so far as I know).
They did not "give up their faith" - what they did is like crossing your fingers when you say something to save yourself or to help another person. Would you have liked to have seen a video of their heads on a platter?
