I'm sure you enjoy pissing people like me off every time you insist on tying extremism to religion.
Just call ISIL ISIL. Just call Al Qaeda Al Qaeda. You can do it I'm sure.
When Manchester was bombed in 1996, no one called the IRA catholic extremists. We called them the IRA. Because that's what they were called and because tying it to their religion wouldn't have solved anything, or done any good to the many Catholics living in Manchester, like those worshipping at St Mary's hidden gem just down the street from the explosion.
