Until the advent of materialism and 19th c. dogma, Western Civilisation was superior to anything Islam had developed. Islam has not aided in the development of the modern world; in fact civilisation has only been created in spite of Islam. Proof of this resides in the 'modern' world and the unending political-economic and spiritual poverty of Muslim states and regions. Squatting on richer civilisations is not 'progress'. Islam is pagan, totalitarian, and irrational.
A nice summary of Islam's supremacism. Please open up a Koran and read these passages. Keep in mind of course that the PC Marxist multi-cult will have us believe that none of these verses has any impact whatsoever on Moslem or Arab culture. The Arabs were annointed by Muhammad who is Allah in the Koran, as the race which would conquer the world. This universalism is a key aspect of Islamic doctrinal theology.
