However, the nutballs have been in charge of Islam so long that people really aren't free to discuss the hadiths or the Koran, so what they do talk about in the eternal quest of all human beings to discover morality and salvation are principles and standards which are strictly extra-koranic.
That way you can find the correct path and not run afoul of some nutcase looking for people to kill for "insulting Islam".
The Islamic world is, at this time, a fruit ripe for the picking by whatever Christian groups can get there.
