Let me try it this way. According to the bible if a person denies that Jesus Christ is the Son of God then that person is not a Christian. If he calls himself a Christian yet denies Christ he is not a Christian. If he calls himself a Christian yet denies Christ through his actions, such as being pro-abortion, pro-gay, democrat etc then he is not a Christian.
John 14:21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
22 Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world?
23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
24 He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father’s which sent me.
While all men sin those who love Jesus try to keep his commandments. If they don't then Jesus is not in them and they are not Christian. (This is greatly simplified but hopefully you get the point) By refusing to keep his commandments (or even try to) they are denying Christ and are thus not Christian.
If a moslem does not follow the koran then they are not really moslems no matter what they call themselves. To follow the koran makes one a terrorist (as the koran commands acts of terror and war against all who are not moslems). Therefore all 'moslems' are terrorists.
The twist is that even those nominal moslems who don't commit acts of terror support those who do (else why haven't they hunted the terrorists down?)
Moslem = terrorist
By definition of the koran.
