The problem is not IS. The problem is a frustrated and disturbed 17 year old who took the first source of identity and outlet for his anger he could find. Are you seriously suggesting that this kid going on a train and start swinging an axe was islamic terrorism?
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
