Hasn't the western Romantic movement always exhibited favor towards Islam? Its simplified creed initially appears similar to that of the Deists, and its fusion of religion and state is arguably mirrored in Rousseau. I have heard that even the Romantic nazis were attracted to the creed.
Alfred Rosenberg, Hitler's chosen ideological theoretician, praised Islam for its anti-Semitism (really, anti-Judaism) and characterized Islam as the "manly religion, while Christianity is the womanish".
He felt that a truly Aryan religion would fulfill the exact same cultural functions in Europe that Islam did in the Middle East, forming a theological rationale for total war and conquest, the liquidation of unassimilable populations and the propagation of the race (through numerous wives as breeding machines, etc.).
