“A fundamentalist Muslim is one who follows all the teachings of Islam, a normal Muslim is one who picks and chooses which teachings he will follow.”
So the guys who fly planes into buildings are following their religion, the unthreatening guy who lives next door might as well be an atheist.

A fundamentalist Christian is one who follows all the teachings of Christianity, a normal Christian is one who picks and chooses which teachings he will follow.
There, fixed it for you.
It’s easy to be a fundamentalist Christian my friend, “love the Lord with all your heart and love your neighbor as yourself”.
Sadly to be a fundamentalist Muslim involves following some pretty nasty doctrines, Jihad springs to mind.
