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.
Islam was spread by conquest and in particular, by the lure of the spoils of war. The cult around Muhammad was only affirmed and deepened when he started handing out war booty. Thus was Jihad the central pillar of Islam. Without war and the distribution of plunder, no one would have joined Muhammad's cult.
The Jizya tax on Infidels is of course a tribute payment, or plunder to be taken from non-Moslems. This tribute payment is a ransom which protects the non-Moslems conquered by Muhammad's cult, from further Jihad predations. If the non-Moslems join the cult, they don't have to pay this head-tax. Historically this was one important reason why non-Moslems 'converted' to the Meccan moon cult.

Narrated 'Amr bin 'Auf Al-Ansari:
(who was an ally of Bam 'Amr bin Lu'ai and one of those who had taken part in (the Ghazwa of) Badr): Allah's Apostle sent Abu 'Ubaida bin Al-Jarreh to Bahrain to collect the Jizya. Allah's Apostle had established peace with the people of Bahrain and appointed Al-'Ala' bin Al-Hadrami as their governor. When Abu 'Ubaida came from Bahrain with the money, the Ansar heard of Abu 'Ubaida's arrival which coincided with the time of the morning prayer with the Prophet.
Jews and Christians can live under Moslem rule if they pay the Jizya poll tax and resign themselves to be second-class knaves under Moslem oppression, existing at the pleasure of Moslems.

Narrated Ibn 'Umar:
Umar bin Al-Khattab expelled all the Jews and Christians from the land of Hijaz. Allah's Apostle after conquering Khaibar, thought of expelling the Jews from the land which, after he conquered it belonged to Allah, Allah's Apostle and the Muslims. But the Jews requested Allah's Apostle to leave them there on the condition that they would do the labor and get half of the fruits (the land would yield). Allah's Apostle said, "We shall keep you on these terms as long as we wish." Thus they stayed till the time of 'Umar's Caliphate when he expelled them to Taima and Ariha.
Muhammad distributed booty to attract followers to his cult. Obviously to obtain booty, war and brigandage were and are necessary. No war, no booty, no cult members.

Narrated Anas bin Malik:
When Allah favored His Apostle with the properties of Hawazin tribe as Fai (booty), he started giving to some Quarries men even up to one-hundred camels each, whereupon some Ansari men said about Allah's Apostle, "May Allah forgive His Apostle! He is giving to (men of) Quraish and leaves us, in spite of the fact that our swords are still dropping blood (of the infidels)" When Allah's Apostle was informed of what they had said, he called the Ansar and gathered them...Allah's Apostle replied, I give to such people as are still close to the period of Infidelity (i.e. they have recently embraced Islam and Faith is still weak in their hearts).
Islam
was formed in the immorality of war, Jihad, plunder, rape and
supremacist annihilation of the Pagans, Jews and Christians. For a
Westerner with an advanced Liberal arts degrees, this proves that
Islam is peace.
