The west crossed the Rubicon when Martin Luther stood up to the Roman Catholic Church breaking the hegemony the RC's had over western society. This brought about the Renaissance, and then the Industrial revolution freeing up humanity from the ball and chain of a defunct 2000 year old version of society. Eventually the Church and State went their own way and society flourished.

Islam has never had such a moment. Name a single Muslim state known for its progressiveness, science, secularism, child and woman's rights. You will find that it does not exist.
