Just when you thought ISIS couldn’t sink to any lower level of barbarism....
It’s tempting to call for genocide against any and all members of ISIS and their relatives, spiritual or literal, but, ISIS is a belief system, not a truly separate entity from the rest of the human race. Eliminating (and they MUST be eliminated) by one means or another, those ISIS affiliates who are active is the simple part of the problem.
It’s an idea. Destroying an idea, even a horrible, barbaric idea is virtually impossible.
