Let's be fair. Whatever the majority of Muslims, globally, may or may not believe, I have certainly met Muslims who self-identified strongly as Muslim, who were observant of the five pillars of Islam in most of the traditional senses, yet who were willing to believe that parts of the Quran are metaphorical and not literal, or who disagreed with traditional and literal interpretations of various parts of the text, and some of whom even believed that the text of the Quran considered canonical by Islam might not be the precise information revealed to Muhammad by Jibril.
I've probably met at least a dozen or more such Muslims, including an imam colleague of mine. I am told there are many, many more such out there.
It does seem like there are a plethora, a superfluity of literalists and fundamentalists among the world Muslim community, but I hardly think it's fair to say that every single one of the 1.6 billion Muslims on earth are literalist and/or fundamentalist. Even just statistically speaking, it would test the bounds of probability for there literally to be zero progressive Muslims.
That much is a given. However, it is still sensible and necessary to ask how well-equipped to deal with progressive thinking, literalism, fanaticism and violent extremism Islam is.
