Only a fellow muslim would say Isil is not islamic....
Think if it in terms of a Christian saying members of the KKK aren’t Christians...
Big difference, you'll see Christian churches and other Christians come together to denounce the KKK whenever they show up to stage a rally. They may call themselves Christian but only they and the hard left believe they're Christian.
OTOH, how many mosques or groups like CAIR denounce ISIS??? Our muslim president even denies they're islamic and says they're just a JV squad, no big deal.
“Think if it in terms of a Christian saying members of the KKK aren’t Christians...”
I don’t think that’s a good analogy. KKK wasn’t/isn’t Christian.
I know what you are saying, but that is not a good analogy. A Christian can point at his Bible and say that the KKK are not Christians for reasons A, B, and C (e.g., 'love thy neighbor as thyself', 'we are all made in the image of God', etc).
On the contrary the ISIL member can point at his koran and say he is just following his book, and the disputing muslim could not rebut this claim.
