It's important to remember that this isn't just ISIS that's barbaric, they are just making very public media events of how
ALL of the Middle East are barbaric in this way. This is how Middle Eastern Muslim society is structured!
Saudi Arabia ( our ally ) legally, publicly, decapitates about
100 people a year. Iran, Iraq, Saudi Arabia, all of the middle east, legally, publicly; behead you, death by hanging for being Gay, cut off hands for stealing, stoned to death for being suspected of extra marital affairs or rejecting a mans advances, gouging out an eye, public chemical blinding, flogging & caning.
