I completely agree. ISIS is a fundamentalist Islamic organization. Muslims who don’t follow the Koran are like Christians who don’t believe in Christ.
I have no doubt there are many Muslim heretics in the world. They may say they’re Muslim because they were raised that way, but if one were to question them on which Islamic tenets they follow, one would find they’re basically unbelievers. They are similar to Christians who believe Christianity evolves with the times and no longer believe fornication, divorce, or homosexuality are sinful.

That is where your assumption could cause you your life.
A muzzie who ‘finds religion’ must go on a killing spree as per the Koran, a Christian who gives up on his religion just becomes a lax Christian but does not become a danger to his environment.
