I have heard that there are Christian evangelicals who thinking about the so-called end times in which there will be a major battle between Christians and Muslims. When I worked for a progressive agency years ago one of my coworkers discussed this idea. I was scared and repulsed by the idea.
In a fight between two religious beliefs I would choose neither one. I’m not surprised that the so-called Islamic State is drawing on the idea of the big war between Christian and Muslim forces in their version of an end times. Humans, for your own sake, you must choose neither. Atheists don’t start wars and we don’t enjoy blowing ourselves to bits.
