This is a crime against their own people, an affront to civilization everywhere. This is heritage, history and building blocks of all human society. I believe that this one act more clearly defines members of IS IS as not just terroristic, but barbaric as well. Every Middle Eastern country, Europe, Asia, South America and North America should unite and stop these crimes against all that is good in the world. ISIS' barbaric behavior is a show of ignorance, intolerance threatening 5000 years of human advancement and a signal to destroy modern civilization. It must end now!
