Atheists are notorious for wanting to rid the world of religion (read Christianity) and their stated reason is the violence promoted and carried out by religion (read Islam).
Oh yes, atheists will bring up the 5 or so abortionists that have been murdered over the last ten years (I'm not suggesting that that's ok). And some will go back a millennia to rant about the crusades and inquisitions (I'm not suggesting that those were ok). Anybody with a brain knows that those behaviours are impossible to square with the teachings of Jesus. So the question becomes, Why aren’t there Christian terrorists? Here’s one explanation.
“If your fundamental [world-view] is based upon a man dying on the cross for his enemies,
If the very heart of your self-image and your religion is a man praying for his enemies as he died for them, sacrificing for them, loving them.
If that sinks into your heart of hearts, it’s going to produce the kind of life that the early Christians produced - the most inclusive possible life out of the most exclusive claim - and that is, this is the truth. But what is the truth? The truth is a God become weak, loving, and dying for the people who oppose him, dying forgiving them.
