ISIS has caused no end of pain and death to people in their way, plus the destruction of ancient monuments in Iraq, Syria, Chad, Mali, Niger, as well as parts of Sudan, Libya and Algeria.
ISIS is an extreme form of Islam formed in their tiny cult-like minds, it is anti-everything. It is being used to destabilise nations and creating insecurity. Most Muslims do not recognise or understand their specific doctrine, it is not normal Islam. Which is why they have to radicalise vulnerable or angry people to join them or act on their behalf.
If the US and the UK had not invaded Iraq for 'regime change' and removing Saddam Hussain, ISIS would never have happened.
Yes, Saddam Hussain was mean to his people and the Kurds, but he kept these type of cults in check. The US hasn't invaded North Korea, Bahrain or Equatorial Guinea to help their people.
The West's lack of cultural understanding of this region, meant changing the status quo in Iraq, turned a 2nd world developed country into a 3rd world one and war-torn one. As a result, sending waves of insecurity all across the Middle East, further into Africa and parts of Asia.
The point of this is to show that ISIS is not anti-semitic per se, but anti-West. Of course, they hate Christians, any other religions, Liberal Muslims and those of no faith too.
