Part one, how about US army with sniper and bombs? They have nothing to do in Iraq, so what gives them right to go there? So US army can go there and kill civilians and it's not a big deal when a Saudi sniper goes there it's a big deal. So your point is invalid.
Part two, same thing you have in saudi where they use religion and speak for God and control every aspect of life, but it's alright in Saudi, but when IS does it it's wrong. I'm not saying that u support US army, neither agree with the system in Saudi Arabia, just the hypocrisy from the mainstream media.
They call PKK and YPG heroes, YPG and PKK are same shit, just PKK and YPG are not threat to US right now, but u never know!
